Dota Auto Chess, a very popular custom game mode for Dota 2 is being turned into a stand-alone game by Valve.
The Dota 2 arcade is full of interesting games but nothing has really come close to Dota Auto Chess, looking at it right now it has over 125K people playing just this one game mode. It also has over 8 million people subscribed to it, to give you another idea of just how popular it is. Based on player-count, if it manages to keep it for the stand-alone version it would put it into the top-5 games on Steam.
Originally created by Drodo, Valve actually invited them to their offices back in February to see if they "want to collaborate directly with us". Seems it didn't work out, as Valve said in the blog post "we both came to the conclusion that Valve and Drodo could not work directly with each other for a variety of reasons". So instead, both Valve and Drodo are working on their own stand-alone version of the game while supporting each other, although the newer one from Drodo is a mobile game. A group at Valve is now at work to make the stand-alone desktop version, with more information about it to be shared "soon".

It's interesting to see Valve getting back into making games, especially since Artifact flopped pretty hard and they're now revamping it (or so they say). They also have a big VR game coming up sometime this year that was teased before and now Dota Auto Chess. Hopefully they will eventually remember Left 4 Dead, Portal and Half-Life…
I'm quite interested myself, I like the idea of Dota Auto Chess so to have a proper stand-alone version with a decent tutorial would be very nice. Right now it still feels quite rough, but the idea of it really is good.
