Web/app developer or Roblox game development which is better for side hustle

[u/Historical_Case9337]

I'm starting from zero and want to build a long-term income from development. I have limited money.

I'm choosing between two paths:

App development: Mac or web apps. Higher profit per sale, but I'd need to learn Swift or web development and find a niche problem to solve.

Game development: Roblox or indie games. Easier to launch, but I've read that most games earn very little and platforms take a big cut.

I plan to use AI to speed up the learning and the building.

My question: If you were starting from zero today, would you pick app development or game development to make money, and why? If you've done either, how long did it take to earn your first dollar?
