@Seth_Wachhaltamittel What he should do considering price points is depending on how many hours of content and assuming it's the average amount of quality which you see in that genre. I would say reasonable price would be 10$ to 15$ dollars but have the game go on sale frequently for around 7$ and you'll get way more sales overall.

Another key point is to really focus on getting a large amount of people to play your game rather than looking to charge people the most to play. Especially if he's an indie developer because from what I've seen some of the most outstanding indie games that are incredibly unique and a drug to play are almost always 10$ to at most $20 so he really just needs to stay in that price point.
