Final Fantasy Crystal Chronicles:Echoes of Time

I feel this game will sell pretty well. Not only does it have 4-player co-op with Wi-fi,but it's also cross-platform with the DS and Wii!This is due to Square-Enix creating and putting to use,the new 'Pollux Engine'. This is the first game in this gen to take advantage of wi-fi capabilities like this(To MY knowledge anyway),and this is a sure-buy to me. Opinions?

The 4 player Online co-op sounds good. I would like to play that. I like the Gamcube one too.
I think it will turn out to be a good seller
