And here's my open-source report card:
http://osrc.dfm.io/larsiusprim... Nicolas Canasse, developer of Evoland, *created* the Haxe programming language. It's totally open source. Here's his open-source report card:
http://osrc.dfm.io/ncannasse Here's Sean Hogan (Anodyne/Even The Ocean)'s contributions:
http://osrc.dfm.io/seanhogan That's just off the top of my head.
The open-source programming language Haxe is strongly represented: three of the charities include the Haxe Foundation itself, OpenFL (recently featured on Slashdot), and FlashDevelop, the most popular open-source Haxe/ActionScript IDE. The fourth is Ren'Py, the Python-based visual novel engine used in award-winning games like Long Live the Queen and Analogue: A Hate Story.
The games themselves are Magical Diary, NEO Scavenger, Offspring Fling!, Planet Stronghold, and for those who pay $6 or more, Anodyne, Defender's Quest, Evoland, and Incredipede, as well as 6 soundtracks.
7 of the 8 games are cross-platform across Mac/Win/Linux, and all are DRM-Free."

It's called "trade dress" and it isn't uncommon. Seven Towns claims ownership of its Rubik's Cube color scheme for example. Recently Apple successfully sued Samsung on trade dress grounds for the visual similarity of their products. It's look-and-feel infringement. If the claimant has a powerful enough brand and can show enough similarities, they can easily prevent competitors from diluting their trademark with a trade dress infringement argument.
