Widescreen Gaming Forum

Hey there, been a while since I posted here. I will start with my situation, scroll down for tl;dr
I recently got my hands on three projectors for a very good price. I knew I would not be able to use them at home much. But I bought them anyway because of an upcoming fundraiser I will be helping out with. I figured I could use one of my TH2G and the projectors to set up a place for people to play and charge some money. Unfortunately due to policies of the organization we wont be able to charge money but my gaming rig should still help some by attracting and keeping people there. I already have the screens (bedsheets) ready to set up and I just need to work on the software side of things.

tl;dr
I need game recommendations to let visitors of a fundraiser try on a triple projector rig. Here are the requirements:
All games must be non violent
Games should be inexpensive (20$ or so, will consider higher costing ones if I want them for myself)
Racing games must support steering wheel with force feedback
All games must work at a resolution of 3072x768
Hud stretch is allowed, missing or cut off hud or ui is not
The games should be easy to pick up and simple.
They should run well on the following system:
Core 2 Quad 2.66 GHz
8GB Ram
GTX 280

I have already chosen Race 07 and Portal

I am also looking for racing games that support the following:
Triple Head
Force Feedback
LAN Head to Head
a P4 3GHz 2GB ram 512MB video card
