I suppose we're the 'non-engine' games. There's also POL, obviously, Ekaiyo, and PokeQuest.
EDIT: Well, as for what DrCoolSanta said, there will always be ways to cheat in single-player PC games. I'm doing a multiplayer thing, so we can handle logic at the server side. However, even if you use binary for maps, some technically proficient guy can just bring up a hex editor and go to town. This is just an engine, anyway, so you should be able to edit your own maps.
