I don’t mean obvious ones like Minecraft. I’m looking for interesting ones like Runescape for instance
There’s always Valheim…
But I host Titanfall servers. People are able to play on them using the Northstar client, a mod for the game that lets you connect to community servers, as well as mod the game in general.
Minecraft, Veloren, Valheim, Core Keeper
Also Bombsquad
I’ve not played it in years, but Soldat was always great fun. Server requirements are pretty much: potato.
Jesus I had forgotten about Soldat
I adore Soldat, that game was a large part of my childhoot. They recently released it for free on Steam and have also come out with a sequel
Skyrim together, if you’re particularly into jank.
Terraria. It’s a sort of hybrid between a minecraft 2d and an action RPG, really fun game with lots of content.
You can play it as standalone or as co-op and the server component is included in the game for you to host it if you want.
Tho If by interesting you mean MMOs, there are emulators for a few of them, WoW is my favorite (TrinityCore, AzerothCore), but know that opening them up to public use is illegal (copyright violation).
Edit: added github links to wow emulators.
Yes, I said it. I stand by it.
There’s some reverse engineering port of WoW server, for example TrinityCore
If you don’t like minecradt you probably won’t like these 2 much either but I’ll leave it here for anyone who might be interested anyways
Gmod and brickrigs (basically a sandbox Lego game but you have access to a massive community made workshop)
Core Keeper
Project Zomboid is worth looking at. It’s not my kind of game, but it’s great at what it is (top down zombie survival crafring)
Maybe I’m old, but I loved hosting Open Arena, Teeworlds and Cube 2: Sauerbraten.
To further my little mention about Runescape though I meant classic I believe there are efforts with the modern-day one: https://github.com/Open-RSC/Core-Framework
You can also host final fantasy 11 servers: https://github.com/LandSandBoat/server
All FOSS games that support multiplayer usually allow to host games. This includes Frozenbubble, Battle for Wesnoth, 0 A.D., Freeciv, OpenArena and UFO: Alien Invasion (and probably many more).
Garry’s mod. Doesn’t use a lot of resources (compared to newer games like Satisfactory), and you have an almost unlimited amount of content and things to do because of the Community Workshop.
Space Engineers is really fun. Kind of a cross between Minecraft and Factorio, but in space.
