Before its launch, Goko was announced to have hundreds of board game licenses, with most of them never being specified. I remember hearing that early on they were working on Citadels, for example. They thought their gaming platform was going to make it really easy to implement board games. Instead, it made it really hard.
The funny thing, to me, is that they got gobs of investment and gobs of board game licenses because their system was supposed to be "cross-platform" and "HTML5". The result they got is not very cross-platform and not very HTML5.
What do I mean by "not very HTML5"? They shoehorned basically everything into one tag, <canvas>, so that they could have complete control over their whiz-bang animations. The canvas tag is a crude stop-gap. It doesn't take advantage of the browser environment. It makes graphics in spite of the browser environment. There's no precise definition of HTML5, but it's certainly not about taking an element that's been around since HTML4 and bloating it with JavaScript until it pretends to be a freaking iPad.
And all this time, there already was a cross-platform, truly HTML5, system for playing board games. A system so expressive and flexible that a single programmer can implement two whole games on it in his spare time. That system is called Isotropic.
