Long time PC gamer, going back to the TSR-80 from Radio Shack, the Commodore 64/128 and Amiga.
Played a LOT of the Battlefield series up through Battlefield 4. I'm not the best shot and I can't stand all the bunny hopping, but I was consistently in the top 1% of the world for win/loss ratio (primarily played 64-player conquest maps as an Engineer) because I know the ebb and flow of each map, where the enemy will be concentrated, what locations are most important to hold, etc. But one day Punkbuster just up and global banned me. When I appealed it (never used a cheat in my life) they said they didn't know what cheat I was accused of using, just that my account was flagged and I was basically SOL. So I no longer support any games that use Punkbuster.
Played a ton of Left 4 Dead (1 and 2) back in the day. And the Total War series of games.
Still play Rome Total War II with mods. Not a fan of the weakness of the AI in the series though, it's been an issue for a long time.
Played the remake of X:com but haven't gotten the sequel yet.
Was a fan of Sid Meiers Gettysburg back in the day and there's a spiritual successor in Ultimate General: Gettysburg and Ultimate General: Civil War. It doesn't exactly capture the magic of the original, but it's enjoyable nonetheless.
Same with the new version of Dungeon Keeper (called War for the Overworld). Didn't exactly capture the magic of the original but was a fun jaunt. And same with Carmageddon, played a ton of the first but the most recent "Max Damage" game hasn't grabbed me as much.
Galactic Civilizations II: Twilight of the Arnor was the bees knees, GalCiv III less so. Endless Legends and Endless Space, Crusader Kings II, Europa Universalis, etc.
Presently mucking around with Civ V: Gods & Kings a bit, trying to play harder difficulties on huge maps and see how well I can hold up. Giving Emperor difficulty a stab at the moment and keeping up (play on Marathon setting so it's a long game)
Also picked up The Sexy Brutale which is a point n' click adventure/puzzle/story game that has a lot of character and is something my wife enjoys watching me play.
Tried getting into Cities: Skylines but didn't grab me. Elite Dangerous found the controls too wonky. The only Fallout I've finished was New Vegas. Bethesda just fails to make me care about the storyline or characters. So while I at first get invested in the exploration aspect of Fallout 3 or 4, eventually it wanes thin and I get bored (same with Skyrim)
Witcher 3 was fantastic. Game Dev Tycoon was a fun game as well. Guild of Dungeoneering lost my interest fairly quickly. Pillars of Eternity didn't keep me invested either. Dragon Age: Origins was fantastic but I haven't really enjoyed the sequels. Stellaris was fun at first but loses luster in the midgame. Tried getting into Prison Architect but it failed to keep me interested. Darkest Dungeon was fun, challenging and atmospheric, but the end game becomes a depressing grind.
Enjoyed some Indie games in The Age of Decadence and Dead Age. Completed This War of Mine and The Banner Saga, but found both to be utterly depressing (Banner Saga being the worst)
Telltale Games The Walking Dead series has kept me invested in the story and characters (unlike the tv show) although you're only given an illusion of choice and most every outcome is pre-determined, you just get some different dialogue for the most part based on your choices.
And I have a slew of games I haven't even gotten to because Steam Sales are more frequent than my free time lol.
