Well, finally finished reading that very meaty article. Salivating at the prospect of GTR2 even more now.
3) Multiplayer has been improved over GTL, which can only be a good thing. 28-30 cars looking good online at the moment. That's plenty of cars in my opinion. 36 or 52 sounds great on the marketing sheet, but do you really want to race most circuits with that many cars?
Grand Am Cup races in the United States have upwards of 75 cars in them. At Mid Ohio there would have been more (if you can believe that) but the pit stalls were limited to 75 so during qual they actually had to eliminate 5 cars. I don't know if it's a USA mentality thing that bigger is better...seems to me that Euro race series have smaller fields, but 24-30 cars online is definately more than enough. There were like 60+ cars in the Rolex Daytona Prototype race and I remember the camera crews interviewing Eddie Cheever and him disgustedly yelling that "this isn't racing, it's bumper cars out there!"
I have gottent to know some of the drivers in the Grand Am Cup series and when you talk to them and their crews, I don't think any of them actually like racing in that environment. There is so much pressure to get ahead of the field that it almost turns into combat on the track, and there does not seem to be the policing in the US of drivers and behavior.
