ACC is a lot of things, but expensive is not one of those things.
I think they could get away with charging a lot more. There's a lot of products on the market that are thought of as high end just because you pay more for them. If you under value your product, consumers will too. If people paid twice as much for Kunos content they'd probably automatically hold it in higher regard. It's just how our ape brains works unfortunately. Kunos could easily sell their physics as a premium product and charge higher prices. I know gamers will give out about the lack of game in ACC but the car simulation is class leading, which is a trump card in the simulation market.. It would bring in more funds for developing the game side of things. My guess is the majority of customers buy it during a discount anyway, I've certainly never paid full price for any Kunos content..Last time I checked it was about 1/3 of the price you would pay for the same licensed content in similar games.
It's as if Kunos never got the memo.
'Expensive' and Assetto Corsa Competizione should never be used in the same sentence.
