What game can you recommend for a 32-bit system, preferably coop?

I would love to find a game that I can play with a friend over a local area network.

Factorio. its lightweight, can be run on both 32bit and 64bit, and its honestly endless fun with a massive modding community.

Risk of rain 1 is great fun! very light requirements

GTA San Andreas, it should work I think.

Gmod 100% such a easy game to run and makes life so much more easier

Star wars Empire at war, Minecraft, Lego star wars the complete saga, Roblox, Garry's Mod,Battlefront 2 classic,Starbound,Stardew valley,Town of salem kinda those are all the games that i could think up and find on my own lists i hope this helps

Play left 4 dead, Good co-op Game forsure!
