I liked the ones with the high payouts.
I'm not much of a collector, but when a friend comes I want a wide selection of cars to choose from, and several in different categories (several DTM's, several typical tuning cars, a bunch of un-modded exotics, several race cars, ...).
You don't have THAT much choice in Arcade, so you gotta buy them, so you need money, so big-payout-seasonal-events are very welcome.
If the high payouts are an issue for PD, I'd be equally happy with something like this:
Seasonal championships or a grouped set or races.
Winning the champ. or all the races nets you a prize car.
Now, a fixed car will have ppl complaining that they already have that car. "Booo useless!"
A random car will have ppl complaining about their 'bad luck' getting a lousy car. "Booo I wanted the other one!"
So... let them select one car out of a selection of - let's say- 5 cars (that are similar in power, type, ... ).
Any thoughts on this kind of setup?
Edit: Oh, and I'm perfectly fine with unrepeatable. Well... lower or no payouts for a second run.
