Don't look too far in the pictures but in motion the difference is obvious,

You know, I'm gonna be honest and say something that might get me banned from the racing sim club.

Prettier cars haven't made me enjoy racing games more.

There, I said it. I've grown a bit weary of all the visual comparison talk I hear between Gran Turismo, Forza, and now Drive Club. I really just do not care all that much about which one looks best. I had every bit as much fun with GT3 when it came out as I did with GT5. It's the racing that's important to me.

Drive Club interests me, not because of how it stacks up visually with Forza, but because it's something a bit different. I really like the idea of being in "clans", so to speak.

This isn't a shot at the OP but rather an expression of how I think something important gets lost in these comparisons.

I dont think its fair to compare GT6 with next gen game. GT6 is current gen and it looks really good regardless. But this is my rating.
After E3 Demo
1. Forza 5
2. Drive Club
3. GT6

Now...
1. Drive Club : it seems that everytime they show a new video, the game becomes more improved and look a lot better. The last Video with the sunset cause me to put this game higher than Forza 5.
2. Forza 5 : Forza 5 looks impressive, but for a next gen it lacks features that should be in this game such as dynamic weather, day and night, still uses static images for background.
3. GT6: GT6 looks impressive but some reason I cant  stop feeling that this is the Gran Turismo 5 that we should have gotten at the beginning. But for a current gen, it ranks very close to the likes of Forza 5 and Drive Club and that alone is impressive. One dissappointing thing about GT6 is that still no "real" damages and better customization of cars.

Well Forza 5 looks far better than the other two.

The have clans in Forza 4 and Forza Horizion and I'm sure they will have them also in Forza 5 there called car clubs.

When it comes to actual content both Forza 5 and GT6 will be miles ahead of #DriveClub.  As a matter of fact I don't think that it will have a lot of contend since you can platium the game by just owning the PSN+ edition so the full retail version will probably only have more tracks and cars but not a lot of other extra content.

GT6
33 tracks (7 new) with 71 distinct layouts, more coming each month as DLC
Custom track layouts in 50x50 km areas
1200 cars (all from GT5 plus a bunch of new ones) more coming in DLC

Driveclub
At least 2 tracks, unknown
At least 10 cars, unknown

Forza 5
At least 5 new tracks, unknown
120 cars

The two games that come out first have released the least information.

One of my best mates jammed Forza yesterday and this is what he had to say (copied and pasted off his fb page) btw this guy is totally unbiased he owns all systems.

Got to jam the Xbox One today at Tech Ed; they had Killer Instinct and Forza 5 on display, so I watched Forza and jammed KI. The vehicle graphics and the smooth imagery on Forza were crazy awesome and hyper smooth, though the background and environment generally had lackluster textures and I expected way more detail (and it is a launch title, probably rushed to release like all launch titles so not knockin' the box). But it was an interesting taste of what's going to soon happen graphically this coming gen when triple A developers get their some stuff out; Capcom, Square etc.

Forza 5 cars look amazing. Problem is everything else on the screen looks very Xbox 360

Driveclub on the other hand seems next gen when you look at the entire package.

This is just my opinion but Killzone SF, Infamous, and Driveclub look next gen. None of the Xbox One launch titles look next gen. And it doesn't look like Xbox One will receive a next gen title until Titan Fall
