You want the wii. Loads of fun. We have about 7 games for it and wii sports has everyone crazy especially tennis and bowling. We've played Madden football and it is a real charge to actually throw passes using the remote. I would suspect all the sports titles that will be made to take advantage of the wii motion controller are going to be fun, Can't wait for Major League Baseball and NHL Hockey.
My 9 year old son is a Star Wars game fan and he swears that they will have to make a Star Wars Laser sword fighting game for Wii.
