✦ AI summary

Grey Goo is an RTS game with an interesting story and presentation that suffers from significant technical issues including frequent crashes on modern PCs, alongside gameplay that players find uninspiring and overly reliant on unit rushing rather than tactical strategy. The AI units lack responsiveness in combat, and the core mechanics feel dated compared to more modern real-time strategy games, leaving most players disappointed despite some appreciation for its concept.

Problems to run on modern pcs, and god how can these units being so stupid ? If you make some units at one point of the map and send them automatically to another point, they won't answer to any attack and just die without minding. Stupid. Missions are so so, its a old rts gameplay where you just have to make a lot of more units than the ennemy, or you're finish. No strategy here, just rushing, always and always. That's bad and old gameplay, games should be more intelligent than just brute force.

In the 2 hours I have been playing this game it crashed 2 times. It also automatically sent a bug report to the developer without letting me review what data is being sent. I know it is a common a practice, and I also think it deserves a thumb down. I do not like developers treating my computer like an open house for them. But I guess I gave my agreement to this by accepting the EULA or it is somewhere in the menus enabled by default. Stupid me for not noticing it, shame on the devs for this being the default. The game itself is a simple RTS with nice presentation and at least from the first few missions that I have played the story and lore looked interesting. The gameplay however is very uninspiring.I do not think I will continue playing it especially with the game crashing so often.
