Sounds pretty simple.
Describe/summarize a non-simulator game in a nutshell by using "X Simulator".
Examples:
Super Meat Boy – Death Simulator
Corruption of Champions – Fetish Simulator
Shadow the Hedgehog – Edge Simulator
Ect.
Of course, avoid naming games that are actual simulators, as well as games that already have the simulator tag/in their title. And try to avoid repetition of games with the same tags, but you can still use the same tag for a different game! Death Simulator can apply to lots of games!
