I love golf....Get Outside, Lotsa Fun (my own acronym). And I found Tiger Woods 2010 really picked up my own nuances in real games. Like always finding the rough, drives that don't reach fairways and water hazards are always in play, even when they aren't. The only thing missing in the game is the friends and a few drinks, which is easily (and for the better) fixed by inviting the friends I normally golf with over.
When it comes to the WII, personally, I'll be looking for games the closely simulate (as best as one can) real life in their application. I think a baseball game that makes use of the WII motion plus sensor would be up my alley.
