I don't share your point of view. Zynga - which is what I consider a web startup - has been at the origin of a revolution in the game industry. At the same time Activision did with Call Of Duty, this is one of the first company which leads the XP + items revolution. That was the first time you saw XP + items in a game from another style than RPG. This is also the reason of the success of the Call Of Duty franchise: COD 4 was the first FPS to have XP + item which were previously reserved to RPGs. Nowday, you can't find a game without XP + items. These things came from companies outside the game industry - except Activision and a very - very - few others.

The energy for example is now a main game design and monetization component you find in many, many video games published by the industry now and this is Zynga's invention. Also, Zynga uses big data far before any other big publishers did - except Valve.

My advice (I work at a gaming company) is to hold all your IP close as possible. Game design, art assets, source code, whatever. You have a right to own it so why not hold on to it for a while until you establish a solid competitive advantage.

Sorry, I think what they are doing has nothing to do with a video game IP. They are doing a product which solves a problem: it teach to code.

For all those common misconceptions (ie. see my other comment below), I strongly advice the codecombat devs to be careful of what is told from and about the game industry.
