Clutch based... try GTR 2, Race 07/GTR Evolution, Live For Speed, rFactor.
GTR2 is the number 1 FIA GT racing game, while Race07/GTR Evo (Evo is an expansion to Race) are mostly touring cars. Live For Speed sucks, I think... the cars feel too floaty... and rFactor is too mod-heavy.
They're all sim racers, so be careful if you're used to rubbish like GRID where it feels like you're driving floating boats.
Space was my issue also, until I got this wheel stand pro.
Mostly got it in preparation for GT5 in November, but it works well for my PC too.
No more setting up and packing away the wheel.
Just unfold the stand and plug it in!
Despite how it looks, it's really quite stable.
