A game based on beating high scores shouldn't matter if you can delete the save file or not. There's no story so what would be the point? Name a game like that where you deleted your save file with the hours it took you to beat it just for fun. I replay my games all the time but that's either to do a speed run or to refresh the story. If this was revelations then I would be pissed and rightly so.
When I played mario kart and my save data with everything unlocked on it was deleted I was pissed and hated that I had to redo all the work I put into it. It still sits there with only 80% of the things unlocked on it now.
I understand the reason for the backlash but I just don't agree with it.
I was gonna wait to buy it used but now I'll just wait for the inevitable price drop and then get it new. I mean it is just a mini-game after all.
