Roblox Game Genres You Can Build with AI
Every genre below can be generated from a written prompt. Each guide covers the core loop, the systems that loop needs, three prompts of increasing quality, and what goes wrong most often.
18 genres, 18 playbooks
The loop is different in every one of these, and so is the prompt that produces a good first build. Start with the genre you actually want to make.

The most common reason a generated Roblox game comes out flat is that the prompt described a setting instead of a loop. "A horror game in a hospital" gives the maker nothing to build; "players search a hospital for four fuses while something hunts them" gives it an objective, a threat and a win condition.
Each genre has its own version of that distinction, along with systems it can't work without — persistence for a simulator, server-side hit detection for a shooter, undo for a sandbox. The guides above spell out both, so you can write a prompt that produces something playable on the first pass rather than the fifth.
Once it's built and published, the genre matters again: what gets a horror game played is not what gets a simulator played. Every guide closes with the promotion approach that actually works for that audience, and links straight into the creator marketplace to book it.
Choosing a genre
Which Roblox genre is easiest to build with AI?
Simulators and tycoons. Both have simple, well-understood loops — collect, upgrade, repeat — so a generated first build is playable almost immediately and the remaining work is balancing numbers rather than writing systems.
Which genre is hardest?
Shooters and puzzle games, for opposite reasons. Shooters hinge on server-authoritative hit registration that has to be right or the game reads as broken. Puzzles need exactly one intended solution per room, which takes human playtesting to guarantee.
Can I mix genres?
Yes, and the most successful Roblox games usually do — a tycoon with pet collection, or an obby with a racing leaderboard. Describe both loops in your prompt and say which one is primary.
Does the genre change how I should promote the game?
Significantly. Horror sells itself through reaction footage, brainrot through short-form clips, RPGs through longer build guides. Each genre guide here ends with what works for that specific audience.
Know what you want to build?
Skip the guides and describe it. The maker works out which systems your loop needs, generates the map and writes the scripts.
