Good games for 3€ or less

LiEat.

Games < 3€ actually : https://gg.deals/deals/?maxPrice=3&minRating=3

So i just watched your games on Steam, you seem to like FPS. But i don't see many FPS actually at 3€ or less.
Maybe you should try rainbow six siege if there is again a free weekend ?

You played a lot Cities XXL, Sim City 4 is on sale actually, maybe you would enjoy it ? https://gg.deals/game/simcity-4-deluxe-edition/

Sleeping dogs definitive edition is a good investment if you like a good story ?
Deus ex Human revolution if you like stealth ?
Radio commander is original and worths a try if you like strategy.
And there is X3 terran conflict / albion prelude, an old masterpiece if you have a lot of time and love space.

edit : thanks to you, i hope you'll find what you search

Also it's not under $3 but I seriously recommend playing Dragon's Dogma or Trails in the Sky If you haven't already.

The Henry Stickmin Collection - pure comedy
you can find ppl selling their keys on steam trades

Just Cause 3 is also fun, blow stuff up

Risen is a great RPG

check deals on gg.deals and isthereanydeal.com

Risen yes, need get used to the controls but pretty immersive world like gothic series.

As Risen and Gothic was mentioned maybe you're not aware of The Chronicles Of Myrtana: Archolos yet. You'll need Gothic II Gold Edition to play.

if you're into old school games , you can grabe tomb raider games and thief , deux ex and legacy of kain for cheap 0.78$ on sale

you should edit for your preference, since i hide most sport/racing and stuff i don't like. just above already show 300 games
and install the extension so you can hide ignored game (optional)
btw how to use link in this site???

Not sure if it falls into the price range, but if you like souls like metroidvanias, I HIGHLY recommend 3000th Duel.

Two that were mentioned already, but I want to vouch for them. Just Cause 3 and Sleeping Dogs are absolutely worth it for that price. With JC3 you can get over 50 hours of complete chaos fun easily, and even to 100 if you want to 100% it. And Sleeping Dogs is just a truly fun experience overall.
