Unity is free up until you make a sizeable chunk over your lifetime (200,000). But if you want any real traction, you'd publish on steam as well. That's where the eyes are, which is $100 per game and 30% of your revenue. Then after that you also have to advertise and market it to some extent. Sure 70% cut sound brutal, which it is, but the point people keep forgetting is a chunk of that % goes back to Apple. Something other platforms dont have to deal with, unless the developer publishes it to the App store itself (then you'll be double taxed from unity and apple and make even less). Also Roblox rewards you extra Robux for having a game that converts users into paying ones-- if you have a game that converts, and has good attention in their algo they literally hand you extra money. What other mobile platform with eyes can give you this? I think where the plot gets lost is the comparison between Steam (or similar) and Roblox. Roblox is a social platform first, with the ability to contribute to a market via game creation. This is the cause of all the recent safety implementations (and this entire overhaul). The eyes are here, and absolutely more abundant than anywhere else. Also, if you're publishing on Unity, whats your target demographic? As of now it is still free to publish to 16 users, which would arguably be the most converting age group and biggest contributors to ARPDAU and the types of audiences you'd typically see on a more aged-up game engine/ platform. You only need a small subscription on top of that to reach <16 users.
