Yikes. I leave for a while and I get a ton of responses. Let me try to clear things up.
I know that Wii Sports is supposed to be a game that has mass-market appeal, and it does. I also understand that Wii Sports isn't meant to be a ultra-realistic sports game. I'm just saying, Wii Sports does what it's supposed to do, but I would love to see it expanded upon. I want a fully fleshed-out Wii Sports, and while my family can really pick up and enjoy Wii Sports as it is, I can't.
As for realism/depth, I outlined this a bit in a earlier posts, but just little things like being able to position your player in Tennis would add a lot of depth in that there would be strategy, not just mindless swinging.
