The point is to get pre-order bonuses
Thats no longer a 'thing'.
pre-order bonuses tend to just be "early access" to in-game bonuses that you'd get with regular gameplay of the game.
pre-order bonuses are getting pretty ridiculous too..... Pre-Order Assassin's Creed 4 and you get a small foam football. Seriously, what does a football have to do with Assassin's Creed?
idk why anyone would pre order digital, it's not like they're going to run out of the game, if you say preorder for bonuses, my GTA5 preorder bonus was a blimp, but ppl who didn't preorder got it as well, so I assume the digital ppl that bought the game got it as well w/o preordering it
