Casually, people sometimes play the game by trading off the ring. Practically, a 100% run takes over a day. Co op could also be fun for twitch. Would such a run be accepted?

On the other end of the scale, the games true ultimate a compliment is lv999. This would constitute one of those crazy months long marathons. Would this be reasonable to attempt?

Co-op sounds fun. 999 seems excessive. It would basically start with an any% run, and then several days of running through Disappearance Path. Even if you start with a 100% run, then get all the titles, there would still just be a bunch of Disappearance Path grinding to finish.
