Best game racing in which you played ?

Nitronic Rush

Recently or all-time favorite? Recently I would have to say Blur. All-time? Mario Kart 64.

NFS MW (2005) and Burnout Paradise

looking forward to playing Dirt 3

Burnout 3 and Dirt 2. Also Demolition Racer.

Wipeout

Supertuxcart. And it's free!

midnight club 3 dub edition on psp

Need for speed UG 2, and GRID.

MARIO KART

NFS UG2

Pro Rally 2001

arcade wise i like grid, nfs hp 2010 and the dirt series especially the first one

simulations probably race 07 is my favorite, with hundreds of mods and tracks it's non stop fun and i enjoyed the brief R3E closed beta, today it should be open beta on steam so feel free to enjoy it

Wipeout for playstation 1 would be one of the best racing games i've played so far. Also Gran Turismo.
For PS2 Burnout 2
On PC; Trackmania Nations Forever (free)

I'm not a big fan of racing games.

forza motorsport 4 and the super old v-rally 2 :D

Re-volt!

Mario Kart for wii ;)

Mario Kart and Mad Riders

Burnout Paradise

Loved Re-Volt (so funny to play, even today) and Trackmania United (so much fun, various gameplays and an awesome community !).

Need For Speed: Hot Pursuit 2

I loved being chased by the coppas!

Road Rash for windows

GRiD is pretty good and I liked NFS:SHiFT too. In rally theme I like DiRT and DiRT 2. It's funny how all of them have this "i" in its name. =)

Sonic & All-Stars Racing Transformed.
Nuff said.

Rollcage, and Rollcage Stage 2

If you haven't played them then I feel bad for you because they're awesome.
