While the game is lacks optimizations for CPU (especially if AI is present on a large map), it presents many features that make it nearly unique in its genre (seamless strategic zoom, very diverse factions). There are also quirks that can make the game a little bit frustrating, such as pathing (I'm looking at you bumper-ball Aeon engineers!), but overall it's a decent strategy game that still keeps its place at our LAN-parties (eh, for more than 10 years already). Every fractions has a different approach to weapon design that shapes its the strategy (e.g. Cybrans sacrifice many defensive capabilities for ones that are more suitable for guerilla warfare). Also low-tech technology does not get entirely obsolete during late-game which adds even more variability. For instance, T3 AA sacrifices AOE damage for accuracy so T1 bombers may actually have better damage overall damage output for the same amount of resources unless the AA is complemented e.g. by T2 AA which would shred through those bombers almost instantly. This variability may present a few gotchas to new players (e.g. tactical missile defense structure varies greatly in effectivity between factions); however, it also makes more strategies viable in multiplayer games. There's an active community around the game (FAForever) that still keeps providing balance patches, maintains repository with mods and maps, and it is even facilitating ranked multiplayer games. Some of these mods fix the original game's issues. Some of these mod such as a new AI (Sorian AI) that partially solves CPU-heavy management of the AI are already included in FAF by default.
The game contains so many catchy stories that listing them would take hours - I really appreciate creators' sense of humor, e.g. fairy land made me laugh like an idiot far too many times (hello H.C. Andersen) . I will probably never see my childhood's fairy tales in the same way. Probably best RPG I have played so far, totally worth every cent.
