Hi

I'm doing the same. I'm going to play through them all in order (except 11, don't do online ones, and not sure whether to play X-2 either)

I have played and completed some of them before but I'm gonna play through them again too as my aim is to complete them all including defeating all superbosses which I've only done on 8.

I'm in the final dungeon on 2, good luck ExQuentin!
