Yeah, that's why people should stop. I didn't buy the season pass crap, and I just sold the game back. I'm kinda upset I bought it in the first place. I am pretty sure I will not buy the next one... I really don't want to support them anymore. Saying it's not going to die is a safe bet, but they have been selling less than the last couple instalments, I believe.
Tney may have sold less on bo2, but that's because black ops 1 sucks, so black ops 2 would also, and it did. And regardless, it got over 1 billion.
