ok so i was going to get the original version of the game but i remembered i still have an extra hundred in my "secret money stash" so i want to get a 'better' version if i can (i didnt pre-order if that matters), is there a list of the different versions and what they include somewhere?

hmm i thought there were more than that. wasnt there multiple versions each with a few different items? like one had a canteen etc?
