Graphically War World is done rather well for an XBLA game, especially for $10. Most of the time seems to have been spent on making the game look good. This gives the game a little more polished look, until players get a camera angle that looks out among most of the battlefield which causes the frame rate to drop. The music in the game is well done and fast paced, and works well for having large robots clash on a large battlefield.
Overall War World is a reasonably fun, good looking XBLA title. The biggest problem is mech balance, which hopefully can be fixed in a later patch.
