SSVOpenHexagon VS crawl

Open Hexagon, re-implementation of Super Hexagon

Yeah, that is interesting. The github page is under an AFL license which contradicts his Steam EULA in multiple ways.

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.

it's a clone of SuperHexagon (2012)

The product is dual-licensed -- the Steam version has an EULA, the GitHub repository is AFL Licensed.

The source code of the game is available here: https://github.com/SuperV1234/SSVOpenHexagon/

I was wondering if Open means truly Open - and it does https://github.com/SuperV1234/SSVOpenHexagon

Open Hexagon - Super Hexagon

It's probably not as rigorous as what you're thinking of but the devs of DCSS have cited online win rates of certain combinations as the impetus for balance changes before.

In a similar vein, see Dungeon Crawl Stone Soup, a free and open-source roguelike that's been continuously developed by volunteers for 20 years: http://crawl.develz.org/

They are entirely too humanoid. I mean, look at these splash screens: Kiku, Ignis, Chei. While those images shouldn't be taken as canonical, they at least demonstrate the general inhumanity of the Crawl pantheon.

Since you like turn-based games too, try some old-school roguelikes. Many are open-source freeware so you have nothing to lose but time. I've been playing Dungeon Crawl Stone Soup for almost 10 years.

Since Brogue's already been mentioned, I'd add Dungeon Crawl Stone Soup and Tales of Maj Eyal as pretty beginner friendly games.

For people who don't follow trunk, Okawru's gifting has been changed (and arguably* nerfed):

My personal first timer recommendation? Maybe Nethack or Dungeon crawl?

Dungeon Crawl Stone Soup - Free traditional roguelike with fair mechanics and a lot of variety between species/skill/god choices (~25 gods and maybe with the exception of sif/veh and oka/trog, they are very distinct). The tiles are great. There's many developers and they are very welcoming of code or vault contributions. Reducing incentives to play tediously is one of the goals. Easily hundreds of hours of gameplay for free. Playable online (connecting to a server through your browser/terminal) or offline (terminal or tiles version). There have been win streaks of 50+ games with a variety of species/background combos so you know it's mostly fair(it IS possible for rng to give you an unwinnable game), but it's very difficult if your goal is to win every game.
