Hi, Terraria is a 2D open-world block building game, with multiplayer servers.
Although Terraria is a commercial game, the server is available as a freeware download from the copyright holder. Tested with the purchased game: I can connect to a server running on OpenBSD. (The game itself also works on OpenBSD with indierunner; I tested this with the GOG edition.) ok? -- Anthony J. Bentley
