A bit more casual, but I really enjoy Super Shock Football and Play Football Also Melon Golf and Invisible Links
football Backbreaker Football- Play a football player running through 60 levels of defense to the touchdown, with stunning 3d graphics and an unbelievable physics engine. The tackle replays look so realistic. Super Shock Football- Kind of a new, arcade version of football. It's in nice 3-d, and it's just kind of laid back. You customize your team, and try to get to the end zone. You really have to try it to understand it, though.
