I really enjoyed Robocop: Rogue City recently. The combat was satisfying, but also its nostalgia pops and its portrayal of the Detroit of the movies. Peter Weller voiced Robocop and he was really perfect. One of the highlights of the game is his deadpan delivery as you walk around doing minor sidequest stuff like busting guys for graffiti. I always got a kick off him calling people 'creep'
With that said, I decided I'd try Terminator: Resistance which was a previous game of the developer. I don't think it's as strong as Robocop, and it feels foundational in a lot of ways where they clearly developed this formula, but it's still pretty fun to play and it has a ton of Terminator references
One game I played a while back and really liked was Mad Max. It became very repetitive in its gameplay loop, but it really delivered and I enjoyed being a part of its world clearing it up bit by bit. You got to develop your ride so it could contend with all the enemy convoys stalking the wasteland and the hand to hand combat is a satisfying Batman: Arkham style button masher. I also thought it was pretty strong in terms of voice acting with your mutant sidekick Chumbucket being the highlight
Going way back to my childhood, but in the Mega Drive era there was Robocop vs Terminator which capitalized on the bloodlust Mortal Kombat created in children everywhere. I suck at side scrollers so I couldn't get far, but my little mind loved just all the splatter
There have been a bunch of great Star Wars games, but one I've always thought was super underrated is the late-90's 4X game Star Wars Rebellion. You could play as either the Empire or Rebels, and you had to take over planets either through force or diplomacy, build up fleets and armies and dominate. But the thing that sets it apart from other 4X games like Galactic Civilizations is that it has a large cast of Star Wars characters you could use to perform specialist missions (From Diplomacy and Fleet command, to espionage and sabotage). This leads into a core mechanic where a victory condition is combing the galaxy trying to capture the enemies main characters. I love that game to death and usually replay it every few years. The only thing that sucked was its 3D Fleet combat which felt clunky and dated even back in the late 90's when it released, but you can just auto-resolve battles and skip it. You can also build Death Stars and go around destroying planet, but the diplomatic fallout means it's a pain in the ass
