I like the projects of indie developers, because they can at once make x100 and x1000, of course, much depends on luck, nevertheless there are a lot of great examples - Hellblade: Senuaʼs Sacrifice, Hollow Knight, SteamWorld Dig 2, Pyre etc
Want an example - Punch Club $ 1 million per first week!2 developers - great idea and superprofit
Therefore, the developers of XENT --- I wish you good luck and I hope that you will succeed - the more you develop a series of games, at least one of them will definitely shoot X1000!
