I am ok with the content been cut providing it is available as DLC later, so all the preorder stuff and special edition stuff it it shows up as DLC fine, but if it stays exclusive that leaves a sour taste in my mouth. Its basically the best horse in the game, best outfit, weapons, and some quests. It is a practice I will never support. But I am an old school gamer who believes when you buy a game it should be feature complete.
A good test I apply when judging a game is if you pretend the game is at half resolution, no lighting affects etc. cartoony, would you still enjoy the game? if yes then the game is legitimately good, if no then you just like the visuals and not the game.
