EmptyEpsilon VS osu

The engine is built on FOSS: https://daid.github.io/EmptyEpsilon/

Looks like they're working off a fork of a fork: https://github.com/clockwork-dog/EmptyEpsilon/commits/main/

Thorium is great; it's closer to a virtual tabletop for starship RPGs than a standalone game, built around creating interactive narratives. That sets it apart from the more straightforward game-style bridge sims, like Artemis[1] and EmptyEpsilon[2], which have scriptable scenarios with narrative elements but have more fundamentally game-focused mechanics.

All of these get used in a lot of fun ways for live events beyond their design, too. Thorium's "family tree" comes from interactive events at planetariums, and EmptyEpsilon, being open-source with an HTTP API and game-master screen for directly manipulating live game state and pretending to be ships, became a popular front-end for European LARPs.[3]

Empty Epsilon bridge simulator: https://github.com/daid/EmptyEpsilon

The game itself is fun, but the best stuff I've seen is it being reused, modified, and adapted for LARPs and crowdplay.

Out of Orbit is a great and ongoing example, a Finnish escape room-ish experience that also has a Twitch game putting stream chat in the role of the ship's AI: https://outoforbit.fi/ and https://www.twitch.tv/outoforbitgame/about

Empty Epsilon powers the game part, with integrations using its DMX interface and HTTP API to provide hardware interfaces and things like Twitch chat commands modifying the game state.

EmptyEpsilon - a free multiplayer bridge simulator. Each ship is typically crewed by 3-6 people, but you can run multiple ships in the same game or get mods that add/change roles.

"the open source": Empty Epsilon. A little more complex of a simulation than Artemis, but feels much more limited from a mission standpoint, mostly due to lack of development from that aspect. Does away with the "Star Trek" feel of Artemis for a more industrial feeling.

If you want to look at an interesting open source C++ game project that (iirc) uses SFML, you could check out Empty Epsilon.

maybe you only play in lazer, if so replace your account url from osu.ppy.sh to lazer.ppy.sh

osu! (latest version is FOSS)

If you need a screenshot then there's one here: https://github.com/ppy/osu/discussions/23343

there's been a cross platform version for a few years, it's quite nice https://github.com/ppy/osu/

Custom rulesets are posted here. Most of them have instructions on their respective GitHub pages but generally it goes: To install this ruleset put the .DLL file onto your osu/Rulesets directory under %appdata%/. Restart osu!lazer and it will do the rest for you.

{ "id": "txibq9", "name": "osu!", "description": "osu! is a free-to-play rhythm game where the player clicks circles to the beat. The game was created by Dean \"peppy\" Herbert and released on September 16, 2007. It was originally written in C# on the .NET framework for Microsoft Windows, and has since been ported to macOS, Linux, Android, and iOS. It was inspired by iNiS's rhythm game Osu! Tatakae! Ouendan, and also takes inspiration from other rhythm games like Taiko no Tatsujin, Beatmania IIDX, Elite Beat Agents, O2Jam, StepMania, and DJMax. The game is heavily community-oriented, with all beatmaps and playable songs being community-made through the in-game map editor. Four different game modes exist, offering various ways to play a beatmap, which can also be combined with modifiers that increase or decrease the difficulty. The original osu!standard remains the most popular to date. As of r/place 2022, the game had 19,872,585 monthly active users according to the game's global country leaderboards.\n\nThis art is centered at the coordinates (727, 727), a reference to the osu! meme WYSI (when you see it). The meme originates from osu! top player chocomint setting a score worth 727pp (performance points) on the map \"Blue Zenith\", twice in 2016 and 2017. The meme saw a resurgence in 2020 from the top player Aireu after setting a play on \"Guess Who Is Back\", awarding him 727pp.\n\nIn 2017, the osu! logo was one of the most long-lasting, organized, well-maintained, and griefed logos, and continued its trend in 2022. It began as a controversial build due to its large size, and the bottom-right of the circle was heavily disputed with r/Superstonk's GameStop artwork. Despite multiple raids and griefs from larger communities and streamers, the osu! community proved to be indestructible, defending itself and its many allies.", "links": { "website": [ "https://osu.ppy.sh", "https://en.wikipedia.org/wiki/Osu!" ], "subreddit": [ "osuplace", "osugame" ] }, "path": { "T:0-1, 1-164": [ [ 721, 678 ], [ 728, 678 ], [ 729, 678 ], [ 729, 679 ], [ 730, 679 ], [ 730, 680 ], [ 731, 680 ], [ 731, 681 ], [ 735, 681 ], [ 735, 680 ], [ 736, 680 ], [ 737, 679 ], [ 746, 679 ], [ 746, 681 ], [ 748, 681 ], [ 748, 682 ], [ 750, 682 ], [ 750, 683 ], [ 752, 683 ], [ 752, 684 ], [ 753, 684 ], [ 753, 685 ], [ 755, 685 ], [ 755, 687 ], [ 758, 687 ], [ 766, 696 ], [ 766, 697 ], [ 769, 701 ], [ 770, 702 ], [ 770, 704 ], [ 771, 704 ], [ 771, 707 ], [ 773, 709 ], [ 773, 712 ], [ 774, 712 ], [ 774, 715 ], [ 775, 715 ], [ 775, 720 ], [ 776, 721 ], [ 776, 734 ], [ 770, 734 ], [ 770, 755 ], [ 768, 755 ], [ 768, 756 ], [ 767, 756 ], [ 767, 758 ], [ 766, 758 ], [ 766, 759 ], [ 765, 759 ], [ 765, 760 ], [ 764, 760 ], [ 763, 760 ], [ 763, 761 ], [ 762, 761 ], [ 762, 763 ], [ 761, 763 ], [ 761, 764 ], [ 758, 767 ], [ 757, 767 ], [ 755, 769 ], [ 753, 769 ], [ 753, 770 ], [ 752, 771 ], [ 750, 771 ], [ 750, 772 ], [ 748, 772 ], [ 748, 773 ], [ 746, 773 ], [ 744, 775 ], [ 740, 775 ], [ 739, 776 ], [ 735, 776 ], [ 734, 777 ], [ 720, 777 ], [ 720, 776 ], [ 715, 776 ], [ 715, 775 ], [ 711, 775 ], [ 711, 774 ], [ 709, 774 ], [ 709, 773 ], [ 706, 773 ], [ 706, 772 ], [ 704, 772 ], [ 704, 771 ], [ 702, 771 ], [ 702, 770 ], [ 701, 770 ], [ 701, 769 ], [ 699, 769 ], [ 699, 768 ], [ 698, 768 ], [ 698, 767 ], [ 696, 767 ], [ 696, 766 ], [ 695, 766 ], [ 695, 765 ], [ 694, 765 ], [ 694, 764 ], [ 693, 764 ], [ 693, 763 ], [ 692, 763 ], [ 692, 762 ], [ 691, 762 ], [ 691, 761 ], [ 690, 761 ], [ 690, 760 ], [ 689, 760 ], [ 689, 759 ], [ 688, 759 ], [ 688, 758 ], [ 687, 758 ], [ 687, 755 ], [ 685, 755 ], [ 685, 753 ], [ 684, 753 ], [ 683, 752 ], [ 683, 750 ], [ 682, 750 ], [ 682, 748 ], [ 681, 748 ], [ 681, 744 ], [ 680, 744 ], [ 680, 743 ], [ 679, 743 ], [ 679, 739 ], [ 678, 739 ], [ 678, 734 ], [ 677, 734 ], [ 677, 721 ], [ 678, 721 ], [ 678, 717 ], [ 679, 717 ], [ 679, 712 ], [ 680, 711 ], [ 680, 709 ], [ 681, 709 ], [ 681, 706 ], [ 682, 706 ], [ 682, 705 ], [ 683, 705 ], [ 683, 702 ], [ 684, 702 ], [ 684, 701 ], [ 685, 701 ], [ 685, 699 ], [ 686, 699 ], [ 686, 698 ], [ 687, 698 ], [ 687, 697 ], [ 687, 696 ], [ 688, 696 ], [ 688, 695 ], [ 689, 695 ], [ 689, 694 ], [ 690, 694 ], [ 690, 693 ], [ 691, 693 ], [ 691, 692 ], [ 692, 692 ], [ 692, 691 ], [ 693, 691 ], [ 693, 690 ], [ 694, 690 ], [ 694, 689 ], [ 695, 689 ], [ 695, 688 ], [ 697, 688 ], [ 696, 687 ], [ 697, 687 ], [ 697, 686 ], [ 699, 686 ], [ 699, 685 ], [ 701, 685 ], [ 701, 684 ], [ 702, 684 ], [ 705, 687 ], [ 710, 682 ], [ 710, 680 ], [ 711, 679 ], [ 712, 680 ], [ 712, 681 ], [ 713, 682 ], [ 714, 682 ], [ 714, 683 ], [ 717, 683 ], [ 719, 681 ] ] }, "center": { "T:0-1, 1-164": [ 724, 728 ] } }
