I'll let you know how it is in 12 hours plus however long I play it for in one session (which could be hours more... >_<) plus however long I sleep for once my Dad gets back from Asia (he got it in Singapore).
Anyone else got this yet? Apparently it's the best DS game available right now, and it's very innovative without sacrificing game length or fun for the sake of a "gimmick". And it has a shitload of replay value (and not high score replay value, but completion to 100% replay value, so it won't get boring for a long while), but NOTHING can hold a candle to Band Brothers in that area.
