I'm thinking the same. I am stopped at a very good point in the game currently were there is a very clear direction as to where to go but should probably still finish it before I forget wtf is going on. I'm currently on my 4th attempt to beat it and much much farther then I've gotten before.
Finish Lost Odyssey first! I once played an RPG on the NES (Magic of Scheherazade), but then I switched on another game, and thus I never completed MoS
