I would hold out for Paper Mario. I'm hoping itll be a nice mix of side scrolling marios, 3d marios, and rpg (mostly 2d mario I hope). If your looking for long term one player adventure games then just wait... only a week left if your in US.
hm whats wrong with racing games? i gotta tell ya Excite Truck is probably the greatest racing game ever (in my opinion) ... i played it for about 3 hours today. You get REALLY into it.
But anyway, Zelda is always a good way to go. I might sell mine though, im done with it and im probably never gonna play again.
