This is what me and a couple friends are doing this weekend. I have already done some preliminary grinding. I am up to level 5, and just about to decimate the first boss. After that I get the girl into the party (the second playable character after the hero) and the multiplayer co-op radness will begin!
My Secret of Mana posse is not planning to do this in one-shot, but more over the course of a couple weekends. Import beer, Thai delivery, and 3 player Secret of Mana… does it get any better? The answer is no.
