I would say it was about right, but only under a certain power.
Had races with El Pibe and proved to myself that Forza could be very interesting in a league, providing all the cars involved were stock and not tamperered with. PI doesn't make that much of a difference, if you have a decent variation of tracks in the season or what not, the cars with better handling, and the cars that are faster or better accelerating will have their share of freedom. I suppose it would be wise to get 8 racers and do a few races in the same car preferably something like B class, then the do it so the fastest guys have to drive the cars in which ever class with a pi lower than everyone elses.
I'm sure theres a way you can keep the racing as even as possible. Nobody really wants to spread out over 3 laps and never see another car do they? (unless you're winning of course :P) I've been thinking about creating a league but I'm still going through it in my head to determine the best way to do it. I don't think I'm the only one in saying that I don't fancy doing anything more than rougly 10 laps with a pad in my hand staring at a TV screen.
My plot ideas are to have a 2 or 3 lap race to determine qualification but has no point rewards. But a 10 lap feature race does. Also to have a crappy freewebs site or something just to update the point standings.
Not planning a date for the races or anything, and since theres only 8 slots for a race I guess only 8 people can enter it. Unless it was some kind of rally sprint thing, or a hill climb championship (which may work out easier and better to plan out).
The cars are pretty close in that series, and some interesting mix of cars as well, porsches, ferraris, vipers, vettes, spykers and even a morgan (well that's mine). There's a success ballast system which might not be to everyone's liking, but it keeps things close.
