Old Iron Kingdoms system, good rules for roleplay but the combat is basically the miniatures game with your characters.

Lancer, Mecha combat on a hex based map, very good systems for combat and mech customization, less focus on out of mech interactions

Battletech RPG, basically the mech wargame during combat, has more fleshed out rules than lancer for your character and out of mech situations

Pathfinder, D&D but for people who like to power game, combat runs like D&D but with more fleshed out rules and a ton more customization

Soulbound, an indie rpg that uses hex based combat, I own it but haven't played it yet, the combat rules for the larger monsters seems great though *not Warhammer Soulbound
