No preset levels. As soon as I found out all the levels were premade I was bummed out. I really like the concept of making a tank myself since I find the avatars for the tanks in all the other games kinda lame. It made it so I can have the guns I want instead of some combo. As already noted, BP points are worthless later in the game. I want more GP to be avaible. And having the hit points instead of the bubble bar thing from BT2 made it really boring.
