I try to do everything but I never do things I don't feel would be fun. I've never attempted the Excalibur 2 quest as I rather find IX's plot and gameplay to be really splendid and I don't think I could ever rush through it all.

I don't play Tetra Master but its because I quickly get bored. Beyond that, I try to do everything though I have never successfully completed the Coffee quest, Mognet, or the Jump rope game... I really need to pop this game in again...
