Right now I'm playing two vastly different games: Dragon Warrior and Final Fantasy 10.
I always find myself restarting them and creating a new file, usually because I didn't play for long enough in one go.
When I play Dragon Warrior, I must finish the whole game without stopping (which actually is possible, because you can beat the game in 10 hours), or else I just restart it; in Final Fantasy 10 I must at least make it to Mi'ihen Highroad before I stop; otherwise, I restart that game too. :rolleyes2
