FASTEST Game on the XBOX 360 ?

What game do you guys think is the fastest on the console I'm looking for a fast paced game that gets your adrenaline running, I've heard people suggest that Sonic Unleashed is pretty darn fast. I have Forza 2 before and I loved it, but I sold it do to boredome(I might pick it up again)...any ideas ?

Forza 2 is by far the better racing game, but I will admit that GRID did do the whole 'sense of speed' thing a bit better.

rainbow six vegas 2 was short in my opinion so was halo 3 and cod world at war

The one game that got my adrenaline going is Left 4 Dead. I'm sure most people would agree that zombies jumping out at you, and shooting them all sky high, gets you going.

Plus, it has four different campaigns, all at a decent length.

From what I've played, GRiD.

Prototype is a pretty fast paced game. Also the Bourne game.

Blazblue. Measure is in Mph, and you'll **** bricks.

Left 4 Dead is quite fast-paced so my vote go to this game.archvile_78

Burnout Paradise for sure.

So many different interpretations of fast in this thread. So i'll give mine too.

Once your pretty good, i have yet to find something more intense than a good round of Mercs in Re5. SP is nothing to shrug off either.

I've only played Sonic and Forza from what you mentioned. Forza is good, but definitely not the fastest. Sonic is fast (on the daytime levels at least) but that game is pretty mediocre imo. Burnout Paradise seems pretty fast.

Burnout.

NFS UNDERCOVER

any racing game

Burnout takedown and Revenge !!!

Thanx guys ! but I think I'm leaning towards getting both Sonic Unleashed and Forza Motorsport 2.;)

Burnout revenge

Forza was way to slow imo. I liked PGR4 wayyyy more.

Definetly Prototype if you know how to use your skills. You can go through the whole city in a minute or two at top end.
