EDIT: I realize I didn’t really interpret the question correctly on my initial read. This is meant more for old games, not sleeper online games that are just good in their own right without being live service. Perhaps a more fitting answer would be AssaultCube. One of the first multiplayer FPS games I played. There probably aren’t any official servers anymore, but community hosted ones were supported, so I’m sure it’s still around.
Straftat. Free to play, fast paced, 1v1 movement shooter. It’s a wildly under appreciated game that would hugely benefit from a small to medium sized, consistent player base. It does have a paid dlc, that mostly functions as a tip for the dev. The DLC has some cosmetics and a few maps, but it’s not really gatekeeping any of the fun of the game, plus it’s only $5 USD so I just bought it and considered it the price of the game.
Yeah when I went down a terminal config rabbit hole I landed on JetBrains Mono with all the nerd font symbols. Can’t really provide a particular reason I like it over many other fonts, but I just do.
