There is no way in hell I am doing the A-Spec 24 hour enduros unless they incorporate game saves.
1. I have a life--House, girlfriend, dogs, friends, career. I don't have the kind of time to sit in front of a game for hours and hours on end. I shouldn't have to pause the game, which means leaving my system on for SEVERAL DAYS STRAIGHT, to finish one of these. Let alone the amount of electricity the PS3 sucks up. As I'm sure you all know, it is a thirsty, hot machine. There would be a significant spike in my electric bill, I'm sure.
2. I am not burning up my PS3 for a game. I should not be required to risk the health of my system. I feel uncomfortable enough leaving it on for 24 hours straight for the B-Spec 24 enduros. I think Sony should offer some kind of protection for selling a game under their name that expects us to do this.
If a game-save feature doesn't happen, I'm never going to do them. Simple as that.
