Developing a mobile game in 2020 is much more difficult, despite high demands. The competition is getting higher and higher. Ther are billions of Apps and Games on the stores.
Quality is more important
I looked into the App Stores and typed “racing game” and there are so much games with the same concept. Which user will scroll 300+ games down to find the best?
You need to be more uniqe – one selling point which differs from the other. Think about to improve the mobile programme in that way.
Advertisments will become more important
Not only advertising will become more important you need to find all kind off ways to create interest on the mobile players and users.
Early Access could be also some kind of advertising like Minecraft did in the past.
Don’t give up
The thing is, yes the market is competitive but it was always so. And: There will be always some kind of market. The users and players need more. There is no stagnation. Yes, it could last much longer until it will be successfull, but the chance it always available.
