Thanks so much for your reply!
my initial thought was to not overcomplicate the very beginning and the campaign be more of a tutorial with the multiplayer match listings being the endgame, but it seems im sacrificing the actual entertainment part too much at the start. I am starting to think I should start the game at 3 or 4 tanks, this should alleviate the boring tank searching part as well.
Each ai file can be directly edited and renamed, the puchasable files just correspond to the arena round where an enemy uses that file for its own tank.
Is editing the ai file not appealing or did it just go unnoticed?
