Braid was covered by the criteria.

>Finally, we only looked at games launched since 2010.

Braid was released on Steam in mid-2009.

(it might be a false positive; or just as likely there is some utility app or launcher tucked in with it that was written in XNA, in which case it's a match for both engines -- that has happened for a lot of titles)

Braid was not made with XNA. It used a custom game engine. I think it was just on XBLIG?

All XBLIG titles are XNA, Braid was a regular XBox Live Arcade game (XBLIG being 'Indie Games', self-published)

Also XNA isn't an engine.

Depends on your definition of "engine". XNA was a set of APIs and tools for game development. Game engines are also a set of APIs and tools for game development, although usually a bit more integrated than XNA. But before Unity and Unreal Engine became the "default engines" the term was used much more losely, often only for the runtime parts, not the authoring tools.

I'm really hoping Jonathan Blow sees this and responds to it :)

He’s too busy making a new programming language for his next game
