I've heard Amazon is accepting returns on ME3. (opened) I'm going to see if that works for me. I'd rather not support Bioware anymore going forward and I'm really happy that Amazon is offering this option.
I was going to play the game a bit more, didn't do all the side missions, I was somewhat curious what the game would play like if I started fresh and did all Paragon but I think I'd rather just stop playing and get my money back.
FYI, if you purchased from amazon and you're unhappy they are apparently willing to accept returns.
