I considered just getting another memory card in fact, it's just been so long since I played it, I didn't realize what had been erased.It didn't erase my Story mode progress this time so I'm fine with that. I could care less about my "garage," honestly.
And I definitely believe you, this game is ridiculous in terms of difficulty. I'm quite impressed you did all that. I'll just be happy if I beat story mode.
I thought Infinity was the best name they had for it. XBOX One is going to consfuse so many parents and grandparents, just like Wii U probably has ... and Infinity would have gotten across the message of it being upgradeable over time they apparently tried to send, so I really don't understand the name.
