Roblox City

I’m developing a Roblox experience that blends an open-world city-life simulator with classic adventure objectives. Players will drop into a vibrant urban map where they can:

• Fully customise their avatar (skins, clothing, accessories).
• Purchase land or apartments, then build and decorate them block-by-block.
• Earn, spend and trade a virtual currency through jobs, quests and a player-run marketplace.

Your task is to take this concept from design doc to a playable Roblox game. That means scripting core systems in Lua, modelling a mid-sized city hub, and wiring together UI, data-stores and UX flows that keep progression smooth and secure. I’ve already outlined quests, NPC dialogue trees and the initial economy balance; you’ll translate that into working code and assets.

Acceptance criteria
– One seamless public server that supports at least 20 concurrent players without noticeable lag.
– Functional character-customisation menu saving to DataStore.
– Construction system that lets users place, rotate and delete parts on owned plots, with server-side validation.
– Economy loop (jobs, shops, taxes, trading) tied to a single in-game currency.
– Polished tutorials and at least two adventure quest lines guiding new players through the above features.
