Open Hexagon is an open source game that started as a clone of Super Hexagon and has since then surpassed it. It also gives the ability for users to make their own level packs with a very robust lua scripting system. The custom levels can be insanely creative, sometimes creating entirely new games within the game, though most are only hosted on the Steam workshop which requires the user to purchase it there. The GitHub repository also lacks music files for the base game. The game itself is otherwise completely open source and free to play if you compile it yourself. https://github.com/vittorioromeo/SSVOpenHexagon https://github.com/vittorioromeo/SSVOpenHexagon Space Station 13 (and the remake, SS14) is an incredibly unique and feature rich multiplayer role playing game that takes place on a rickety space station in a wacky retro-futuristic setting. It's hard to recommend this game as the learning curve is more like a cliff, but it is far and away the best game that exists for creating unique (and often very funny) stories in. It has a long and complicated open source history that has fragmented it into several unique popular forks, but the most popular one that's fully open source nowadays is tgstation. https://github.com/tgstation/tgstation https://github.com/tgstation/tgstation On that topic I've been playing an SS13-inspired browser based game lately. It's fully open source and takes inspiration from Melvor Idle, but is a much shorter and nicely compacted experience. https://github.com/TBartl/space-station-13-idle https://github.com/TBartl/space-station-13-idle https://spacestationidle.com/ https://spacestationidle.com/
