Your options are
- Lancer, a superhero skirmish game (no OOC rules)
- Heavy Gear, which is VOTMS , but the only thing combustible is the fuel powering your engine (had and RPG once, probably didn't get updated to include all the new toys since then)
- Battletech, a land battleship accident simulator (Full OOC rules and slimmed down mech combat rules for role players)
- Mekaton, a giant robot builder engine (with attached 90s RPG rules)
- GURPS, where you basically stat your mech as a big guy buddy for your small guy character. Highly autistic about everything, but also highly reactive to your autism or lack thereof.
- buncha recent japanese systems, with more coming I never looked into.
