- You want a block-building sandbox you can mod (Luanti is the pick)

Open-source games let you read the code, mod it and play without paying or watching ads. The catch is that the code is open while art and music sometimes carry different licenses, as with SuperTuxKart, where the code is GPL but textures and sound use a mix of terms. The list here covers different tastes. 0 A.D. and OpenRA are real-time strategy, with 0 A.D. set in ancient warfare and OpenRA recreating classic Command & Conquer style play. The Battle for Wesnoth is turn-based fantasy strategy with a huge campaign library. OpenTTD is a transport business simulation based on Transport Tycoon Deluxe, and Luanti is a voxel engine with community games and mods in the style of block builders. SuperTuxKart is the casual choice for an evening with friends on one keyboard or pad. Expect uneven polish: community-made campaigns and online servers vary in quality, and some titles need original game files to look like the commercial game they are inspired by. Check the platform lines below, because Android, macOS and Linux support is not the same across them.
