here is a good list:Fallout 1-3, New Vegas and Tactics
Jagged Alliance 1, 2, Back in Action and various expansions
Harbinger
Shadow Watch
S2- Silent Storm and expansion
Hire Guns- The Jagged Edge
Space Rangers 2 Reboot version
Brigade E5 and 7.62 High Caliber
Escape Velocity Nova
Most are tactical games but that seems to be the only kind of RPG that gets proper magic-less treatment.
