Ive always liked NBA Jam and Hang Time. The 2 vs. 2 is a lot easier to play, but I do like NBA 2K a lot as well.

The Madden games are decent to play still. One of them has really fun mini games, maybe it was 03.

MVP Baseball 05 and 06 were really fun.

Was never really a big hockey fan. Tennis games I never played much. NASCAR i dont really count. Boxing games are boring to me, the realistic ones at least.
