can this game play on vista

Windows Vista (Unlike other Windows) doesn't support backwords compatability so you will have to either reformat or not play you better hope they move to XNA from DirectX9.0c as then you might be able to actually run the game although I'm not sure that even that would work.

but maple story and gunbound can work

Why don't your try the game out first, then?

Well.. i dont think it works on vista yet... but u can try test it...

It doesnt work ive tried it on Vista. soo...Dont bother Xpatch doesnt like Vista. same with gameguard.>:(
