I was thinking that a miniatures game or board game based on something like the Twisted Metal franchise would be cool.
The vehicles could have some base stats: movement, armor (damage mitigation), agility (base to-hit value), and some basic weapons attached to the vehicle. Weapons having range/damage type/damage value/ammo type . Certain vehicles may have a vulnerability to a particular damage type.
The vehicle miniatures could be modular to allow for adding up to a set number of upgrades at a cost of reducing movement and/or mitigation and/or agility.
Just a thought for something different.
