The production value on the voice acting, during missions and briefings are fantastic, and the game looks beautiful both during missions and during briefings. The story, with the threat of “the silent ones” hanging over all three races, is engaging.

Grey Goo wildly exceeds all expectations for presentation and gameplay. While there are a few issues with cheating and infinite units in single player, the multiplayer is rock solid.

Grey Goo is, frankly, fantastic. From the opening scenes through the entire narrative thread of the campaign, you'll want to improve your game if only so you can see what happens next as quickly as possible.

Grey Goo is a successful reconstruction of several classic real-time strategies at once. Is it still quoting the originals or is it already parasiting on them? Little bit of both.

It’s the most purely fun, accessible RTS I’ve played in years.

Grey Goo is an extremely well produced game. Fans of classic RTS games should sample the Goo for themselves because it's the best RTS released for quite some time.

Grey Goo is a traditional Real Time Strategy game, loyal to the genres’ core gameplay mechanics. Additionally, the production values, graphics and music are first rate. It may have a steep learning curve for newcomers, but the intuitive tutorials and UI will guide those interested in the game smoothly through its multiple assimilation levels.

It lacks that final polish games like Starcraft have received where each unit and race has been weighed against every other in terms of cost and utility. Nonetheless, it is a nicely crafted and presented RTS which leans towards the old-school mold.

Two very similar factions dull its edge, but Grey Goo’s old-school take on strategy still makes it one of the most interesting new RTS games in years.

Grey Goo is decent but too by-the-numbers RTS. [May 2015]

If you’re looking for a modern yet traditional RTS other than StarCraft II, you can’t go wrong with Grey Goo. [03/2014, p.68]

Anyone who is a fan of this type of game will surely enjoy this, and the online play and DLC components it makes it even better.

Grey Goo is a symphony of strategy games. The rhythm of base building roots your spine with the amazing soundtrack and visuals providing a solid melody from the wind instruments. Sharp, aggressive strings scream into life with the combat as epic units crescendo in the brass section’s apocalyptic fury.

GreyGoo is a classic RTS game, solid enough to capture its audience. If you like the genre it’s a must have.

Grey Goo is perfect for fans of 90s real-time strategy games and is one of the best RTS games in recent memories not to be called StarCraft II.

Multiplayer is well catered for, and while as previously stated a generous amount of learning time to get familiar with the factions is highly recommended, there’s plenty of fun to be had for old RTS veterans and newcomers alike. One sticking point is the current small number of maps available; thankfully a well-featured map editor has been included at launch for fans to create and submit their own.

The biggest problem Grey Goo has is that it’s far too hard for what it is, which is a fun Command and Conquer-style RTS.

Grey Goo feels like a complete RTS package, built to spec in a time when enthusiasm for the genre is at a low. It helps show there's life yet in the formula pioneered by the likes of Command & Conquer and Dune, and while it might not have the weight to stand up against the likes of Starcraft 2, its own place in the contemporary strategic constellation is secure.

One of the best traditional RTS games to hit the PC in a number of years.

In the end, Grey Goo is an interesting attempt at a simple but effective RTS game.

Perhaps the lack of innovation is disappointing, but the game is so good that it's hard to indifferently pass it by. Grey Goo is the essence of a proper RTS, gathering all the best and recognizable elements from many classic predecessors.

With a solid multiplayer and an epic campaign, Grey Goo is a great traditional RTS.

By most standards, Grey Goo is an excellent real-time strategy game with fantastically unique factions and stunning graphics. Its campaign undermines some of its positive aspects with a steep difficulty curve, some annoying "gotcha" moments, and maps that can make it difficult for expansion.

Grey Goo isn't a paradigm shift but Petroglyph still really know what they're doing when it comes to RTS. They introduce some clever new twists on the formula and tell an intriguing story in the process.

It’s a testament to sound design when the worst aspect of a video game is indeed its actual title. Even with it, though, Grey Goo is a stand-out RTS that has found an expert way of blending old with new to create something familiar but fresh.

If we ever got the C&C game we so much deserve, Grey Goo would be it. By using its roots as a base to build upon, Petroglyph created a very solid piece of RTS history. A must, especially for fans of Westwood's work.

And even if the development team is not necessarily keen on the comparison with Command & Conquer, they do not shy away from it - Grey Goo can fill the large footsteps easily.

Grey Goo is a game designed for old-school RTS fans, with some new design twists. It may have some flaws, but it is definitely worth the money.

Grey Goo might not be as complex or intricately balanced as “that other strategy game”, but it’s still enjoyable and imaginative where so few games within the genre are.

Grey Goo is likely the best traditional RTS not made by Blizzard in the past five years. The cinematic, exciting presentation of the campaign is a big selling point by itself, even if the mission structure and actual scenarios are less than revolutionary.

Grey Goo, if you’ll excuse the pun, oozes originality. It’s a refreshing take on a classic style of real-time strategy gaming.

Grey Goo can be considered the sleeper of the year (strategy game). It is a good game overall, taking classic elements and adapting to changing times, but rather lacking in depth.

Grey Goo is one of the most interesting recent RTS games and right now there aren't many games in this genre to choose from. Real time strategy fans will be pleased but it's definitely not a perfect game. Grey Goo wants to be StarCraft (the atmosphere, 3 races, good storyline) and the new C&C (slow gameplay and minimal micromanagement) at the same time. As such it suffers a bit but you need to appreciate the good intentions.

Classic real-time strategy like Command & Conquer with base building – I’ve missed you. Unfortunately when it comes to battles, brawn is favored over brains.

That "I did my best but failed..." accompanies Grey Goo in almost every aspect. The game is really good but constantly stumbles on small, but noticeable imperfections. Excellent re-creation of the C&C game mechanics without the inherent C&C drive. Lovely base management with solely battle tactics of "grasp all units with a frame and send them to attack". High complexity, which is based on the cheating AI. Balance of a game from 1995 in a year of 2015. [Issue #195, p.82]

It's a solid and entertaining classic RTS event though it's hard to identify yourself with some grey slime.

While Grey Goo is a solid and enjoyable RTS at its core, it simply lacks depth, fresh ideas and most importantly unit variety to have an impact on the genre.

The titular Goo race is one of the freshest aspects of the genre in a long time, and I hope that Petroglyph has some more great ideas up its sleeves for the future.

One of the best real-time strategies for some time, although it’s a shame that despite a few new ideas it’s not really interested in pushing the genre forward.

Petroglyph has sought to make a simple, direct game... and maybe they have exceeded that. Being a good game does not add anything to make it a serious alternative to the big ones.

Grey Goo isn’t a revolution by any means, but it’s a return to classic RTS gameplay that demands strategy and tactics over the mindless onslaught of mouse clicks.

Once again, Petroglyph produced an RTS that is not good enough to warrant its “From the creators of Command & Conquer” tagline.

Grey Goo is a strategy game with an old good gameplay. We spend a good moment with Gry Goo, despite often failing AI and a feeling of tiredness that can happen quickly.

Gameplay is serviceable, and somewhat fun, though it is hampered by unresponsive controls and annoying pathfinding which leads to your troops wandering in the most convoluted way.

Grey Goo is a dry and forgettable B-side RTS with no advantage over other RTSs save the fact that it was more recently released.
