Call me lazy or paranoid or whatever, but I really don't want to have to create an account just to play this game!
Based on the trailers, I'm sure it's a lovely game, and I'd like to give you the benefit of the doubt that you aren't going to maliciously misuse the data you've gathered, but I think it's just too much of a roadblock to put in front of players when A) I don't even know if the game is worth the hassle B) there are loads of other games I could be playing instead that don't ask for this stuff and operate just fine with saving and all that C) there are plenty games that use accounts but also allow you to use a 'guest' account to take a peek and see if it's worth it D) having to make an account and be online makes me worried about the longevity of the game and ability to access it in future E) from what I hear, it's not even a multiplayer game, so why?
