I sold my Wii on ebay. Why? I just didn't play it as much as my PS3. The only positives that the Wii has is:
1. Its party factor
2. Its physical style
3. Classic Games
Thats all folks. The only fun game I played besides Wii sports (isn't the pack-in supposed to be pretty lame?) was Scarface. Shooting worked quite well. Other than that, the motion controls just felt like a gimmick. Sure it was a blast for the first 6 months, but having a PS3 on hand, even with the lack of PS3 games available, I still played my PS3 more. In the end? It felt like i paid $250 for Wii bowling-- fun but NOT worth $250.
Rock on Sony.
