The first two Thief games are seminal titles in the stealth genre, being two of Looking Glass’s most well-known projects. However, unlike most other immersive sims, Thief has no RPG elements to create its system-driven gameplay, but comes off as system-driven anyway. What gives?

In this video I also made a small prototype in Unity of how a game made in the Stim and Response format might look. That project can be downloaded here, though I have not written up documentation for it. The project has been re-imported into Unity 2018.2.4 before uploading.
