Oh dang it that’s a really hard one lol, well there are three that I could never decide on whether I liked em more or not, so it’s a three way tie lol.
1. Team Fortress 2. That game is so much fun as a FPS lol, it’s got high skill curves and matches can get really intense, but if I want to take it easy and have a lot of fun, I can just go ahead and do whatever the heck and still have a blast. (I love a specific communist build where I take a sign “the Stalin stick” with the hammer and sickle on it and do a Russian dance every time I kill someone, it’s so much fun lol)
2. Civilization V. Loved that game when I was younger, still love it now, honestly one of the best sandbox/empire simulators out there, and my favorite in the series. Just so much fun to conquer and build a kingdom.
3. Hollow Knight. An awesome Metroidvania that deserves way more love and attention. Platforming is great, fighting is smooth and fluid, the storyline and characters are great in many ways, and the boss fights are just AWESOME! When you’re doing well, you really feel like a bada** in that game lol. Plus the design and animation are just beautiful, and the feeling of traversing the remains of this ruined civilization, discovering every zone and seeing the text, that feeling can’t really be replicated.

Well that was a long comment on video games lol
