Steam has Assetto Corsa for $19.99 right now. I watched some video reviews of the game and still feel unsure. I have bought Grid, NFS and even the F1 games. I have not played them extensively but casually. What kind of input can you give compared to these titles? Play wise and graphically? Thank you.

And you really should use a good racing wheel with it, makes it a much better experience.

Well I dont currently have  racing wheel. I have always wanted one. The one I have wanted for a long time is the Logitech G27.

Good choice , I wan't that one as well. All I have now is a Val gear "Trans Wheel" from the 90's (to put it simply: It sucks...).

It supports controllers to.  I use a wired XBOX 360 Controller.  Just don't expect to win races online if you play like this.  The same can be said for any other racing simulator really.

I bought AC last week.  Even though it's incomplete, it's awesome. If you are in to racing sims this should be at the top of your list. I use a G27 on a wheelstand pro.  Its probably the best bang for your buck way to go for racing.  I'm ready for a career mode, but it's still alot of fun.  It's going to take a while to become efficient with the feel of the sim.  It's not easy. I would highly recommend it at $20...  I paid $40 last week.  It's going to be a 10/10 once it's finished.
 
Edit: I'd also like to add, that a race wheel to the level of a G27 isn't necessarily necessary...  Alot of the cars will just utilize the paddle shifters b/c they have more than 6 gears.  The Logitech Momo Race wheel could be a good choice as well and is much less expensive.  That's if it's still for sale... You might could find one used on ebay for next to nothing...  I think I have only used the shifter on the G27 for 1 car so far.
