Standard cut for steam is 30% of a sale until some thresholds are hit. Which I'm doubtful 2hu will ever hit. Since it's like 10 and 50 million in revenue breakpoints. I'm not sure how much DLsite takes, but google suggests maybe 20%(?) or similar values. The games are cheaper on DLsite though.
So realistically Zun probably sees 6-10 bucks from a sale depending on various factors.
