The Motives Engine is a Sims-inspired simulation engine developed by Tony Bark. Although it borrows elements from all four games, the engine itself wholly unique in its implementation. The virtual machine, the part that makes modding and expansions possible, shares more in common with BarkVM and Second Life's LSL than The Sims.

Basil VM

Basil (BASIC Application Scripting for Item Logic) is the scripting language and virtual machine that functions. It optionally allows developers to extend an object's functionality beyond fixed motives.

The VM uses JSON as an intermediate representation (IR) with a schema inspired by WebAssembly. Bark argued that he is just one person and JSON was provided for free with every language. He wasn't going to write an intermediate language if he didn't have to.
