As much as I understand people wanting to just pay sub average standards for the game. I'd be more than happy to pay the price of an industry game for this if it was as complete as they say it would be. Though I know people find 70.00$ prices fairly high, I wouldn't mind it, depending on how long the game is (single player wise, re-playability is nice, but something like 5 hours for a full price game is silly (coughTheOrdercough).
If it is a multi-console release (XboxOne, Ps4, WiiU and PC most likely since it was originally planned for PC). I imagine the game may be priced around the 50$ game, depending on how small it is of course, I'm talking like old Banjo Kazooie sized story (I believe it was around 20 hours maybe on average first time around?).
Whatever it's price I'm most likely getting it and happy to support. (please get on PS4, that'd be amazing, if it's on PC that's good too though
