Changing parts yourself? That's neat, but also a useless gimmick, what do I gain from pretending to be mechanic? Not saying that it won't interest somebody, but it's a gimmick. Spraying the car? You can do that with the Wii, let alone Move (which is unlike Kinect actually really precise).

All I'm saying is that Kinect with Forza doesn't offer anything that couldn't be done elsewhere = implementing gimmick's. How many people will buy 150 USD device for these functions? Well I'm afraid that many, but those are really useless gimmicky functions that doesn't enhance the game in any way.

Obviously you dont buy hardware for 1 game. And in a racing game I want the wheel. So of course these extras are extras. 

But they are extras not all possible elsewhere. It's interaction on a car lovers level. Many people go on and on about GT being car porn. And for the car lovers. What more can a car lover want than to physically inspect every part of a car he'll never afford? Learn about maintaining and changing parts on a Ferrari?

Yeah some people wont bother, they just wanna race. But some people will love the feature. It's like having a personal Virtual car encyclopedia. Something you cannot get on any other console.

The main game wont change. But the game will feel far more complete as a car enthusiast game with these features.

If I'm not mistaken GT5 has something called photomode where you can set your cars into different locations, inspect them, walk around them and take pictures. I'm not sure how is that far from what was shown in the Forza demo but to me that seems pretty similar. Also with GT you'll have that in a couple of months and with models that are all looking like what they've shown in the Forza demo. On the other hand Forza doesn't have any future "proof" models, so they might have a lot of work on their hands if you are supposed to inspect and explore more of these highly detailed cars.

As for car maintance, you do realize that would mean modeling everything under the hood in 1:1? Generic and random interiors won't cut it (current Forza). So unless they are ready to basicaly remodel every car in such a detail as Polyphony did on their Premium Cars (see, PD is ahead, again) it won't cut it.

So far all I see are gimmicky functions that doesn't really offer anything new, and I don't think they can come up with something really interesting and revolutionary, that wasn't already done in an old WIi game (Zack and Wiki has both of the Forza functions in some form...).

 360 wheel says hi too yet even Forza 3 (as well as all 360 racing games) steering wheel is an after thought.(there is athe case where  controls are mapped to the right analog stick which wheels don't have.) When  the 911 Turbo S  first came out some thought the wheel's FFB was weak until they learn it was Forza 3 not the wheel. GT3 RS v2 is Fanatec best wheel  I would still get this instead even though it's not for 360. 

 A good wheel still needs good software to take advantage of the wheel.

Actually the FFB isnt considered weak. The rumble is. But Turn 10 got it right. It's just many no real racers understand.

The complete experience for Forza 3 is FFb wheel plus Buttkicker. When driving a real car there isnt alot of rumble through the wheel. Alot of games excessively put rumble through the wheel. Note that rumble is completely different from tension on the wheel whilst turning against forces of nature.

Things like being hit in the rear, the side, over a rumble strip etc, the tension of the wheel being forced left or right is great. But the rumble was designed to come through the entire chair moreso than the wheel. In other words a far more realistic experience.

Selnor, two important things you ought to take into consideration regarding the potential of Forza w/ Kinect:

1) Firstly, there is no way Turn 10 have the time to recreate the mechanical interiors for several hundred cars in 1:1 detail so as to allow someone to perform repairs or upgrades by virtually lifting the hood and fiddling in micro-detail with valves and what not. It would take decades to program.

2) Secondly, have much of an attraction do you really think the ability to be a mechanic is to gamers? The racing genre is the least popular it's been for years, and you want Turn 10 to build a feature that will appeal to an even smaller sub-niche of car-enthusiast gamers? Even those qualified to actually work on cars (i.e. real-life mechanics)... do you seriously expect they're going to come home from working in a garage all day and then want to spend their evening in a virtual garage rather than actually racing? It's farcical.
