Funny (let me explain) that some people would find tuning overwhelming, I mean I totally understand your comment, and agree it likely has much merit...
But funny, for me, because... Back when GT4 was released I had zero interest in race car games... didn't even know that GT series existed.
A co-worker that knew I was a gear head approached me at the coffee pot one day and asked me "so, in a car, what is camber, and what does it do?"
Odd discussion to have with the director if design in an architectural firm, but ok...
(background - he wears nice shoes and a bow tie and speaks eloquently, I am a construction engineer, wear work boots and a T-shirt and have to drop the F bomb to make myself clear... he dazzles politicians and gov't officials all day, I work construction.)
A few days later he asks me how can anti roll bars effect the handling of a car... again, we talk, and that is that.
The next week, he pulls me aside and says, ok, I play this race car game, and I'm thinking about getting a steering wheel, should I get one with force feedback? I didn't even know what force feedback was but said sure, you want to be able to feel what the car is doing... whatever... game geek... you can afford it...
Some time passes by and one day again, he approached me and asked, what does a limited slip do?
OK, so, I finally put it all together and before answering him I ask, so this game you play... you can adjust all that in the game, and it actually has effect on the car?
He gets all smiles and say oh yes, says how you can feel it, and he starts telling me how you can adjust shocks, springs, rear gear trans gears castor etc etc... says he has no idea what he's doing, but appreciates me explaining it to him...
So, now I'm interested and he can tell... and he says come on over this weekend and have a go... this is like mixing oil and water together... ... whatever, I know he likes good beer and I'm betting he's got some in his fridge so I agree.
I was blown away... I might have drove for 10 minutes that evening, the rest of the time he hammered cars around tracks and I watched what the car was doing and we made adjustments... he was happy to get his car dialed, but I think I had more fun... was kinda like a work session for him.
So, overwhelming... is funny to me, because, it is the very... ok, only thing that lured me in.
So, that "co-worker" is now my best friend... and our lives have gotten a lot more complicated, and we no longer work together, but we still get together to play "race cars".
oh, he's still faster than me... even more so when I get his car just right.
