I've played all the games on your list, with the exception of the DQ series. I would recommend Mother 3 if you liked Earthbound. It's a very interesting game, fantastic graphics (for GBA), nice music, but I don't care for the battle system. I almost got to the end, and then stopped, as I do with many RPGs because I didn't feel like putting in the final level grinding effort.

Anyway this is off topic now, more about classic RPGs than it is about DQVI haha.
