Here is a cool new GRID video thats recently been put up on the net.

Press reviews have also all been around the 9/10 mark
Even for an arcade racer, his driving skills absolutely blows. Especially on the first race. Sure he may... have been using it to show viewers what crash damage is like... but to do so many crashes on 3 races... I don't think that was intentional. Yes a derby, those things are crash nightmares, but I've seen better drivers than that.

He's still hitting walls even with no cars near him!
He has to ram into other cars to get passed... The Viper is almost wrecked at Donington Park.
We are talking about GT5p, and i'm surprised you havn't been flamed for calling it a demo, because when it first came out you would have been lynched for doing so by some guys on here.
A very bad response by you there. Please try harder.
Shall I start eh?
Look at GRiD, final game, 43 cars... no clue how many car variations, but I'll bet it's nowhere near GT5

or any other. I can't find any info on that. 16 tracks with multiple variations. £39.99, I'll bet Codemasters charge for DLC. Heck, didn't they once charge for cheat codes? That's more money you'll have to fork out and it wont even come close to the amount of content in GT5.
Now GT5

, 71 cars.. 552 car colour variations for all 71 cars. 6 tracks with again some variations, and supposedly another track coming with an update, and car damage coming out with an update. £17.98, thats not even final.
Heck thats cheaper than a newly released top title PC game like Crysis for example. Usually anything from £23 to £27.
Now correct me if I'm wrong, a demo is a demonstration. Not adding to what's already there and keep adding. It's a sampler. Take it or leave it.
The last time I checked, the only demo of Gran Turismo 5 for the Playstation 3 was GT:HD Concept v1.2. 16 cars, 1 track with 1 variation. Nothing added to it, no updates for it. Free for the public to try. Once again, take it or leave it.
How can GT5

possibly be a demo. It has to be a test bed beta type game. It's like what was it? rFactor a work in progress? Even though you bought it they were still adding to...
Nobody keeps updating demos and adding to them. Do they? I don't recall any... and usually demo's are worse than the final game, so buggy and all that. Even so buggy that it would even crash as you attempt to launch it. EA, NFS Carbon for example on the PC...
