If you like using your head, and are up for a challenge, buy Fire Emblem:Radiant Dawn.
If you're new to SRPGs it could give you close to 100 hours of GP (including restarts). If you're either a natural, or have played them before, it should still clock in 70+ hours.
That's 1 play-through, and this game has an amazing replay value.
Other than that, buy SMG, TP and MKWii, but you have of course already listed those.
If you're into football, pro evo Wii is a fairly good game.
