I find it a bit dissapointing that 5 star general doesn't really do/give anything besides the achievement and the spiffy icon as far as I can tell, I was kind of hoping for some ridiculous weapons/mods to try out since there's already power gained as you go through the normal ranks.

Outside of that it was a really good game, my only complaint being that it can be difficult to find exactly where to get certain materials since you don't have much of an idea of where the monster is if you want to get certain items even if you already know what monster drops what you need.
