There is no way I can play this without comparing it with Star Fox 64, a game I played to death. Although Assault's Multiplayer is no doubt superior, the main story (campaign) is very underwhelming. It feels barebones in a lot of moments, and the pacing is not right.
Again, this may be because I'm used to the pacing and cohesion of the N64 title, but for me, its not a great game.
