Yes for any game without a publisher. Most indie games use publishers so they can get paid while they’re making the game. It’s really only the games made in a basement on weekends that may see a price improvement.

But the customers don’t see this. You buy a $60 brand new game on epic vs steam vs nintendo vs prime vs anywhere else: the game isn’t more expensive on steam because of their fees. The game is still $60, the publisher and studio make less money. In fact steam doesn’t even set prices, the publisher does. Steam takes 30% to use the platform. Is that too much? Maybe, but this doesn’t hurt the customer, this hurts the people wanting the profits, mostly the game publishers.

Taking this down to 10% won’t drop the price of the game, it reduces the amount of money steam gets. The publisher gets more money. That’s what changes. A few small indie games where the studio is also the publisher might drop the price, but they will be few and far between.
