I haven't seen DiRT mentioned in any way, shape, or form.
That could only mean:
1) No one here has played the series
2) No one here liked the series
3) No one here bothered to post about the series.
I seriously hope it's the first, as I expect the upcoming DiRT 3 to be AWESOME!
Anyway:
+1 Cave Story
+1 City Racing (Freeware)
+1 Guitar Hero (any)
-1 Rock Band (any)
-1 Any FPS
