Lol, the guy said FE accidently.He also said Wifi, playing other peoples maps, and voice chat without a headset. Sounds awesome.
Speaking of FE, what are your thoughts on Fire Emblem (title is in the works). I think it's a remake of an older FE game not released in America. It's supposed to have Marth in it :).
Mario Party DS- Well, I've never owned a Mario Party but I have played it with friends. Anyone think it will be good?
Mega Man ZX Advent- Seems like it's going to a great game. You can transform into bosses, and I think a few other models (I don't know that much about Mega Man). I saw a trailer and it had voice acting so that might be cool. I don't think there is Wifi though.
