I was reading about final fantasy crystal chronicals: Echoes of Time and thought that game was great so i went and got that game, had a play of it and thought it was great. The wifi compatability is what makes it so good. Sure if you go to someone elses world it usually lags a bit but thats why most people go invite so people can come to our world. I can assure you people, the game will not lag for you if you go invite. I know alot of you, like me would have got the game mostly just for the wifi. And for you that aren't sure if the wifi will be any good it doesn't matter because the game without wifi is great. It has a great storyline, good graphics and is fun for all ages. So if you have a DS, get the game and you will be having a ball. I can honestly say that you will not be dissapointed. (If you don't like RPG's or Final Fantasy games then it probably isn't for you.) 9.0/10
