Oh if you’re talking about exclusives then pricing is all over the place because they have exclusive in all categories (AAA to indie)…
There’s also more than them in the balance to determine the price at which games sell, 2K games won’t sell the new Borderlands for 60$ while other AAA titles are selling for 70$, they still need to maximise profit and if the market has determined that 70$ is a fair price then so be it.
Anyway I don’t understand why you wouldn’t want the devs to make more money so they’re able to produce more games instead of the launcher company making more money so they can develop “trading cards” as a way to make even more money.
