But, instead of having a reasonable progression system, we force the player to pick up random crap in the middle of a warzone, and run multiple couple minute detours back to base if he wants to use more than 4 basic weapons?"
It's a charming concept with fun to be had, but, once the initial appeal chaffs thin, you're left a game of bewildering design choices.
