So my pc is a crapshoot, and it'll be a while till i'm ever able to afford upgrading. So I want to know what games are out there that are nice and also run on low end pcs.

Posting specs in a sec.

Halo 1

Although the developers are no longer supporting the servers i think you can find some volunteers.

Stardew valley, terraria, pixel doungon

Unturned is a dank game that can run even in the lowest of pcs

The Binding of Isaac; (50h+ spent on steam)
Rimworld; (100h+ spent on steam and a kidney)
Papers, Please. (10h spent on team, but it's a great game)

All of then run even on a toaster.

GamersGoMakers I love that game idk why

bastion, brawlhalla, castle crashers, duelyst, hearthstone, rivals of aether, roguelands, super meat boy, transistor, vampire of the sands, [insert generic clicker game here]

what kind of games do you like

Try out Terraria

I'd say to download NES/Genesis emulators, they have some good games.

welp, AssaultCube used to be my favorite game when i had my poorest pc ever.
PowderToy if you like wasting time(it's mostly a simulator, but a pretty cool one) with chemical reactions.
Minecraft is the best option i can think, it's really fun making stuff and then exploding it. Or just adventuring with your wolf/dog
Half-Life 1 is also cool
