What's Good
MIT. Free Engine at $0. Same codebase for solo and networked play. Browser RPG/MMORPG framework in TypeScript. Studio is $99 lifetime optional — pitch the MIT engine / Free Engine only.
The Catch
Browser RPG/MMORPG TypeScript framework (same code solo + networked) — not Phaser scenes, not Colyseus rooms alone, not GDevelop no-code, not Godot/Heaps. Studio is not the free path.
Verdict
MIT Free Engine for browser RPGs. Studio is optional paid; engine is free.
