Crazy Game Ideas #1: Drunk Driving Simulator2011 Nintendo Edition

I was playing Mario Kart Wii online one night with a friend on Twitter, I started out doing my usually 1st place finishes, but after a while I just started doing bad and hitting everything I possibly could. That gave me an idea for a game...

Drunk Driving Simulator 2011 Nintendo Edition.

The idea is to not win the race, but to just hit as much crap as you possibly can, with the goal being to get as much points as. you can.

The point Breakdown:

Hit an item thrown by you or another racer: 10 points
Hit a course hazard: 20 points
Hit another racer: 50 points
Hit anything under the influence of Star Power, Bullet Bill Power: The value of the thing hit is Doubled.

There is also a combo system as well, you start with a multiplyer of x1.0, but every object you hit adds another .1 to the multiplyer with no maximum ceiling. You have to hit the next object within 5-10 seconds to continue the combo, you get a special bonus for holding a combo from the start to the finish. The combo resets if you don't hit an object in time.

It would be the standard 3 laps, or whatever regular laps the voided has. The courses and the characters would be the usual familiar cast as well, so you know all the tracks before hand and the racers that you can bring your wrath upon. You know that one character that's always a pain in your side? Now you can just rain down havoc on him/her!

There are also achievements to get as well that will help your score:

"Shutout": Hit every racer at least once for a 200 point bonus.
"You Hate Yourself": Hit your own items 10 times for a 100 point bonus.
"Bob-ombs Away": Hit at least 2 racers with 1 Bob-Omb for a 150 point bonus.
"Super Star": Hit at least 3 racers under Star Power for a 200 point bonus.
"Owned" Hit the same racer with 3 items within 15 seconds for a 150 point bonus.

And many more others.

I would like to play this game, I think it would be a way to just smash everything and not worry about trying to come in 1st place. Let me know what you think, anything you would add, remove, fix.
