Personally - I liked and disliked the game. I think that it's a great idea and I'm surprised no one has tried to mod it on games before. I mean - w/Tribes 2, it DEFINITELY could have been done.
Westwood seems committed to making this game a hit. I remember talking with a lot of gaming buddies about how even though piloting ground vehicles kicked ass, the real fun would be piloting Orcas and NOD attack choppers. Well, two days later, Westwood announces that they're gonna make that a reality with a patch that's going to be released "a few weeks from now."
Single-player-wise, the game is pretty lopsided - the weapons need DEFINITE tweaking. I mean, playing NOD in multi, if you successfully are able to plant a nuclear beacon in a GDI base (no easy task) it better be in the middle of the inside of the building, or the "25 megaton" blast, that's supposed to "wipe out everything in a 10 mile radius" won't do jack. The "Personal Ion Cannon" is also basically useless in the fact that it only works well against infantry - but has a wickedly long refire rate - and you'd think something with even 1/100th the power of a satellite ION shot would damage a tank pretty well...nope - barely scratches the surface.
And the multi...OH the multi. If you've played any of the Tribes games, you'll be right at home. When you buy a vehicle, you'd damn well better get in it quickly, because some jackass WILL steal it without hesitation. Secondly, if you get on a team that plays the game like a deathmatch in the GDI vs. NOD mode, you will curse God, because this game is excruciatingly frustrating when you play with a team with no sense of, well, TEAMWORK. Lord knows how much hair I lost when I saw tanks mindlessly shooting infantry instead of a assaulting a base. There is no real way to describe the folly in seeing 5 mammoth tanks, 3 medium tanks, 1 MLRS and 2 Hummers just outside the NOD base for fear of the obelisk they could destroy in about 15 seconds if they just advanced. This game does not suffer fools gladly in multiplayer - and if you're looking for a boom and zoom game - stick to Wolf and Q3:TA.
Bottom line: if you're a fan of C&C - this game is an enjoyable way to spend 29.99, and if you have the BB coupon, 24.99. Tiberian Sun was pretty crappy - but for .01 or free, you can't beat the price. I've seen far more "dedicated" companies screw up FPSes, but Westwood did a damned good job on their first. My only gripe - they shoulda used the Q3:TA engine - because it coulda been prettier.
