Yeah...well while I golded the NSX one at the Nür just out of competitive nature/self challenge, I really hated it in some ways because I had to buy 3 diff NSX to compare for best set up combo with stuff you can't undo and trying out a boatload of mods before finding the right recipe. That takes alot of guesswork at the start and time to the figure stuff out because there are so many possibilities and that was a real headache. To me that takes all the fun out of just logging in for a few minutes and drive. With mods allowed it is really time consuming before you can even start to challenge for times...not ideal if your life doesn't revolve around gaming 24/7.
All the time required for tuning is time you could have spent driving and having fun doing the TT instead of getting brain dead.
The other thing I don't like about this format is depending on the car, even if you gold it, it might cost you more credits just to buy the car and mod it, let alone if you buy 3 to try out diff setups to compare, even if you resell the cars after!
Now for someone, like many others, who got tired of grinding just for cash and because of the lack of events in carrer mode and low payouts...I had left for several months because I got sick of it. Since I came back I discovered on this forum following the 25th anniversary anyone could do the online TTs so I immediately jumped in and loved it. It's the only thing that keeps me hanging on to this game now aside from circuit experience whenever there's a new one.
I might very well skip this next TT and according to stats from the NSX Nür TT members posted here, it seem like many participants get turned off by the idea of spending 1-2 mil and going through all of which I just described to potentially come up short(moneywise)in the end, so I expect participation to fall again.
