Nintendo has a vacancy for Hotel Giant
It's a six-year-old game, but that pretty much makes it perfect for the DS. You'll be designing rooms and adding various hotel-y items, all the while ensuring John Q Guest is satisfied enough to pay the upgrade fee for the ultra-chump room.
All joking aside, the original PC title was a big hit and it should be very well-suited to the stylus and touch screen when it comes out in Europe and -- pending iron-clad confirmation -- North America. Bellboy!
