Warframe is free to play and nothing is locked behind money. it’s got a really steep learning curve but pushing past it is well worth it.

Battle for Wesnoth is a nice and polished turn based strategy game. You need to get used to the sometimes annoying rng hit system, but it can get addicting trying to protect a favourite unit, give them the last hits so they can level up and then faceroll the map.

You could play the hit 2007 class-based shooter Team Fortress 2

Trackmania 2020, you can do the seasonal campaign, ranked and royal for free, and it’s a fun as hell game with a great community. There’s more if you pay, but theres many hours of game play for free and it isn’t time limited at all.

Does require ubisoft connect, but that’s also free.

S.T.A.L.K.E.R. Anomaly a sand-box survival FPS RPG set in a sci-fi version chernobyl, the game is actually a mod of the original S.T.A.L.K.E.R. trilogy games, which are loosely based on the novel Roadside Picnic (1972) and film “stalker” (1979). go check them out if you’re interested or, just go blind in, it’s tons of fun if you like this kind of stuff

I mean, just get the free game every week on the epic game store. That should cover all your free games gaming needs

Path of Exile

If you like music, there are a bunch of good free rhythm games:

• Osu
• Stepmania/DDR - Main modern versions are Project Outfox and ITGmania
• IIDX/BMS - Beatoraja, heres a good English guide to it
  • Neat thing about BMS is that all of the music is made or licensed/allowed for it. The community is strictly against charting copyrighted songs, partially due to them requiring keysounding.
• Sound Voltex - Untitled SDVX Clone
• Guitar Hero - Clone Hero

Note that some of these require or are improved by an additional controller, so they’re not entirely free but once you have what you need you’re set.

Board Game Arena would be my recommendation. Amazing platform that keeps adding games (typically a new game is added every Wednesday). You can play real-time or turn-based, I almost exclusively play turn-based these days since it allows me to check the website whenever I have a few minutes of free time and play through my turns.

Warframe, League of Legends, Valorant, Legends of Runeterra, Genshin Impact, Epic Game Store freebies, I think Rocket League is f2p too now

Mindustry is definitely must try if you like factory and tower defense elements. It’s free on itchi io and its available on f droid as well. The steam version is paid but it’s just a way to support the dev so you’re not missing out on any game feature. Has cross platform multiplayer as well with a lot of public servers you can jump in once you understand how to play the game.

Old School Runescape is still a pretty chill free MMO to play. Granted, you have like maybe 5% of the content available to you, but you could still get a majority of your skills up to 99 and do a a decent amount of questing.

Counter-Strike is a great free first person shooter. There is no pay to win in that game at all and never will be!

One of the hundreds I already own.

You could give a try to chess, specifically on lichess.org

It’s such a deep and beautiful game, so hard to master yet fun and challenging at any level of skill. Climbing the ranking ladder is a true challenge with yourself.

It’s also an esport and a game that you can play at any age.
