How do you make a Roblox game?

The short answer

Install Roblox Studio, open a place, build a map, write the scripts that make it a game, press Play, and publish when it runs. That is the whole loop, and Studio is free. The hard part is the middle: the scripts, the saved progress, the shop, the UI. A map alone is a screensaver.

What a game actually needs to run

Take a zombie survival game. The map comes quickly. Behind it sit the round system, the zombie spawning, the weapons, the money, the shop that sells them, and the data store that remembers all of it when the server restarts. Same story for a tycoon, an obby, anything. The systems are the game, and the systems are scripts.

This is where every beginner hits the wall. Scripting is real programming in a language called Luau, and the honest path through it is weeks of tutorials. Most people quit in the first hour, holding half a map and a pile of red errors.

The other way: start from a game that already runs

There is a second path that almost nobody mentions: start from a finished game and change it. The rounds already work, the money already saves, and you never see a red error on day one. You decide what your version is — faster zombies, a second floor, harder jumps — by saying it in a sentence.

That is what SG ai is. You pick a hand-tested kit (wave survival, tycoon, obby, or steal-and-run), it lands in your own place in Roblox Studio through a small plugin, and you press Play before you change a thing. Then each change you ask for is checked before it reaches your game — and if a change ever broke the game on load, the place goes back and the build comes back to you.

What you need installed

Roblox Studio, which is free, and the SG ai plugin from the Creator Store. That is the whole list. No paid AI subscription, no config files, no second computer. You do need to be signed in to Roblox, because the game you build lands in your own account — when you publish it, your name is on it.

Then what

Then you keep going, one sentence at a time. A game is never finished; it is one change away from being better. The kits cover the four shapes most first games take, and the first one is free.
