HAWX is a good game, if you accept it for what it is.
A console designed arcade game primarily geared towards MP. In that it plays very well. True, the AI in the SP is lame, the views are hard to get used to when playing with the external on but lock yourself to a cockpit only and it's a whole different game.
However, Hawx is the first step towards a combined warfare universe that's currently in development from UBI/Tom Clancy. Land, Air and Sea warfare based individual games being played together in a MMO. Imagine that, 256 online players per server, either on foot, vehicle, ship or aircraft.
