There is a new mariokart style game over on steam called Zero Gear. Apart from the generic race mode there are also wacky extras including soccer (football), ice hockey, american football and even pinball! Steam describes it better than me :p
"Zero Gear is physically-fueled, online multiplayer kart combat madness.
Deck out your kart and character before jumping into one of many different game modes. Outrageous kinematic gameplay and weapons make every round a blast. The potential for tiny vehicular mayhem has never been so humongous! Boost, flip, spin, and slide your way to victory!
Up to 8 players.
Customizable karts and characters.
Multiple game modes to compete in, including Race, Tag, Goal, and Target modes.
Over 15 maps to compete in.
Non-stop physics driven action.
Ridiculous weapons and power-ups, including tornadoes, repulsor shields, and love-seeking L.U.V. bots.

From my brief time with the game it was actually fairly enjoyable - there is still 3.5 days left of the free w/e and at only 500mb or so it is well worth a try imo.
