Plaay.com has a game called Hockey Blast. It's incredibly detailed,right down to having stats for every player of every team, and covers the action on the ice minute-by-minute. Personally, I feel the extreme detail slows the game down, but I think other people here have played it and they may have different thoughts. i'm not sure if the company made a basketball game.
Two Hour Wargames is working on a hockey game that's supposed to be quicker and more streamlined for fast-paced, but detailed games. It's in limbo at the moment along with a football game, but hopefully if enough people generate interest, it'll help get the game released. The company also has a boxing, MMA, and soccer game.
