That's what separates a "sim" game from an "arcade" game. And in this sense, SHIFT comes across as terribly arcade, where GT5P comes across as truly sim-like, despite one having more detailed tire physics than the other. I'm not qualified to comment on Forza, though... which probably makes this comment somewhat pointless... but there...
I think you're right, well, you must be right, that some of the talents needed in either world help you along in the other.
Reflexes, precision, stamina - all needed in the real world. That's why I stick to games or being a passenger in a race car
Trouble is, attacking a corner in a car at speed is terribly frightening. The amount of grip in corners, the ability to accelerate and brake, the G-Forces, rattling, etc is nothing compared to anything you can experience on public roads in a road car. Even going 200 kph on an Autobahn and a lorry pulling over to your lane is nothing if you see a solid concrete wall flying towards you while the engine is screaming away and you can't even hear yourself yelling at the driver.
I agree, Shift might not be as complex as a sim racer if you look at how you can manage weight shift or balance braking vs. turn in. There are infinitely more possible inputs in Forza or GT4.
But, and that's my point, I never felt terrified in Forza 2 nor GT4. Maybe the race classes made me sweat, but the usual suspects? Golfs, even Ferraris and Porsches? Nothing. It was annoying if I messed up a corner and didn't get a top 1000 LB time in Froza, but that was it.
On the other hand, jump into Shift and do a lap even in a measly Golf or older Nissan 350Z on the Ring. You "feel" going over a bump, the car becoming light and steering wobbly. You "feel" the inertia if you take a turn far to quick.
GT4 didn't offer that either, but boy was it beautiful. Take a beautiful car, put it on an beautiful racetrack, look at some beautiful graphics and you also had the challenge to actually
drive the car because it wouldn't do it by itself.
So Forza 3 is out, and they put more "stuff" in it to make it a better game. They made some improvements in graphics, and this was overdue because comparing GT4 (in progressive scan) to FM2 wasn't any real difference. They tried to iron out some of the major flaws of the tuning system.
btw, really, don't get me started on how they handle bottoming out. The lap gets flagged, and that's it.
What a terribly stupid thing to do: in FM2, 80% of all LB cars constantly bottomed out. But instead of fixing the engine - they simply penalise it.
On the upside, there are more interesting tracks. I know, a circuit track is a boring thing to look at, but there were no amazing tracks in FM2. They fixed that, too.
But still, they haven't really evolved anything. And really sorry to say, the on board view is just a very bad joke. Once you're accustomed to Shift, there is no going back.
To conclude my rant: You can have a good time in Forza3, no doubt. But much of the fun isn't for me. Race and cars first, fancy gimmicks second.
GT4 had some awful AI, but the presentation was real nice. They wanted it to be nice. What a nice way to go for a Sunday ride, and race some other nice car in doing so.
It's good to have these games on both consoles, and I highly doubt we would see either franchise if it weren't for the console wars.
But more "stuff" doesn't equal a better game.
