the former is in IMO(and IGN for the matter) a pretty shitty game, mostly because its hard for the wrong reasons(getting decent cards), duel academy is IMO the best for the advanced, i am right now playing the championship 2009 version on my DS and its pretty decent so far, but i am having a horrible time getting meteor dragon, red eyes black dragon and meteor B. dragon(i need him to summon him after the fusion duh), probably because the packs on this game are not specific(aka no dragon cards pack, only a begginers one instead can give red eyes and meteor dragon which was fused with other packs, thus getting the cards become a lot harder).
