I very much liked the game for its new style of combat, both aereal and ground. The vertical stuff is amazing. AMAZING!!
I think that the amount of weapons that you can use in the game is pretty good, but it would have been really cool if you can take over one of the big wathcers, the guys that fly and shoot huge bombs and have a minigun...maybe I can! didn't finish the game yet!!!
I think the game is really worth buying and there could have been some areas of improvement but maybe a patch or expansion are coming up with this very much needed overhaul of the flying system and much more stuff.
The game IS GREAT, but there's always room for improvement in this kind of games, where they just opened a door to new ways of fighting and having a blast flying a guy with roketpacks!! THAT IS COOL.
