Could you build this?
Partial A Luau-based instance, signal, and service model is buildable with open-source Luau, but faithfully emulating Roblox's engine behavior and 3D world is a very large, fidelity-sensitive effort.
What it would actually take: Luau can be embedded from open source, and the instance tree, signals, and services are CRUD-like data structures. The hard parts are matching Roblox's scheduler and API semantics closely enough for real games and building a 3D renderer and physics layer. This needs experienced game engine engineers and extensive compatibility testing.
