MW4:Mercs would be my goto now, I have to try getting that to run, I loved that game, just don't bother with MW5, it's the most infuriating game ever.
The AI of your lancemates is so bad it actively prevents you from having fun in most battles (even with AI mod). Most missions are supremely boring auto-generated and even the story missions are mostly not interesting. And there are popup turret emplacements and tanks spawning out of nowhere all over the maps.
Almost no tactics possible.
I've also failed to hitch horses with the "Battletech" game that's out there. I think it's supposed to be a translation of the tabletop game's mechanics to a computer game, but I slid right off it like a cow pat on a kitchen window.
Part of it is that I generally don't care about some random little mercenary company on some little world somewhere in the periphery, and that's what this story is. It hits you with this HUGE cut scene that plays every time you launch the game, it takes a LONG time to get through menus and cut scenes to get to the tutorial, and then the game is simultaneously giving you how the controls work tutorials in text, while characters hit you with story dialog, and then I didn't want to play anymore.
