Sure. I used to be more into FPS games. My most recent habits with them were playing Planetside 2, and Team Fortress 2. I tend to prefer relatively realistic games, or at least ones where I find the action relatable. I like gun fights to be more about taking cover, maneuver, and avoiding getting shot because getting hit once tends to be serious, perhaps debilitating or lethal. I don’t like FPS games that allow bunny-hopping or strafing around in the open as an effective way to avoid getting shot. And I don’t much like grinding for upgrades, especially, as I wrote before, when they’re carried over despite death, so it’s just a matter of grind time and/or paying, which is one of the things I did not like about Planetside 2.
Another FPS that’s about my style is the Arma series, though I haven’t gotten much into it, as I’ve been more into other games in recent years, and it seems to have a high amount of time put into getting into the action, only to usually have me get quickly killed because I haven’t developed my skill and understanding enough yet.
The Hidden & Dangerous games were good at being realistic and gritty World War 2 games. There was also a mod for Battleground 2 I liked that made it very deadly and more realistic.
I’ve enjoyed Doom, Quake, Quake 2, and several others… there was a mod for Unreal Tournament I liked to play multiplayer with a lot, where the only weapon was a blaster that killed in one shot.
