Hmm... I initially said (and voted) DQ5 in my head, then something better came to my mind: a Wii Points card. There's just so much good stuff on WiiWare anymore, and that should easily get you a game or 2 without any more cash. (Then again, if you start getting into After Years, you might need more points...)
