I have been a Pokemon fan for a while and I ordered this, no regrets or dissapointments. This game was bafore they "Redone" the way the pokemon were animated in this game and alot of the pokemon will look different than they do in R/B/Y and so on. In the US we got this game but it was redone and is Pokemon Blue. Do not get this if you think it has different pokemon or wish to trade to American Versions,if a Japanese game is traded to an American version it will corrupt data on both games.
