As for the main topic, Spactime Studios did quite a good job with the pc/mobile cross, they especially did an amazing job in cross-platforming between mobile and pc, OTM should take a look at how they did it. In terms of graphics and interactive, CH obviously wins. Spactime mmos have been pretty much running on the same game engine, with the same dungeon mob systems (clear a dungeon, next level, repeat). While CH has the open world experience that few mobile mmos have been able to accomplish(not to mention most mobile "mmo's" are "imaginary" games, where you actually have to imagine your characters hackin slashing, throwing firebolts, and shooting twigs at mobs, when in reality you are just staring at a bunch of pictures and flashy numbers), with its graphics improving as new game engines are developed.
But in general, I think CH would come to pc one day, but first they need to change their company name, or (trolling now

If CH actually would come to pc, I think it would come via google chrome, since CH by then should have a fair partnership with google via android (another reason for this guess being, well, spacetime studios going through the same procedure).
