I reached a certain part of a mission and that was it, could not complete it due to game killing bug and there was no way to redo it at the time.
Then i could not get the DLC i had payed for, simply would not work.
I am to blame though, pre-ordered the game, pre-ordered and bought the season pass, then went and did the whole thing for A:CM.
But lesson learned at last, now i will wait till the game is out before i drop cash, not writting off anybody, but my days of blindly buying before launch are now gone.
Back to the old fashioned way for me, wait for game to come out, see the reviews, and buy and support if good.
