The Costco version comes with Wii sports, an extra Wii mote, and Zelda, which is a franchise I love, so good pack in game for me. I plan to buy SSX Blur immediately and then just see what it's like. I'm using it on a regular tube TV, so I won't be able to evaluate it's modest 480P graphics until I get a new TV. When I get the new TV, then I get an Xbox Elite (more probable) or a PS3. I haven't really been paying attention to many of the games for the Wii since I was just so dead set on finding one and having so much trouble. I don't even know if I need to buy more accessories for this thing? I don't know anyone that has one to ask questions about it. However, everyone seems to be looking for the damn thing. Here's hoping I don't break my TV screen with the Wiimote!
I don't have any kids, but my co-worker who bought it does (2 boys- like 4 and 6 years old), so I'll find out what they think of it on Monday when he brings mine in.
