Eternal Sunshine of the Spotless Gamer, eh? I don't know that it's really necessary. Wiping my gaming memory wouldn't change the "different every time" factor of most games in my preferred genres, and losing the wonder I had for FF6 when I was 17 would just make it...well...different. And not in a good way. At 32, I'm older, more experienced, more cynical. The game just wouldn't feel right. Ditto for Chrono Trigger.
