Query: Quite simply, a really fun game....

This game is great: easy to pick up and learn; fun game control; good gameplay; solid graphics; just enough story line to add some depth to the gameplay; overall, an excellent game. Although the graphics are not exceptional (honestly, they could use a little work), I have to admit that this is a super-fun game to play that mixes just the right amount of challenge and reward to keep you hooked on "defending the galaxy...". This is a keeper, and definitely a better alternative to other vehicular combat games ... Get this game, you won't be sorry.
