well, in case of C2 this message could look like:
"We would like to release our game on PC, however our game jitters even on computers playing FarCry 4 1080p 60 fps. So we have to wait just a few months for better Node-Webkit."
It's not that bad. But it does require you to troubleshoot, use an older Node-Webkit (and seriously where the hell is the basic option to include icon files & instead of defaulting to the generic NW icon?!) that works etc.
I've never been more happy with C2 than in recent times. With top performance on iOS, decent performance & features on Android and still great performance on PC/MAC... Sadly, Linux is still broken though! But at least NW guys are aware and hopefully they will fix the dependency on the outdated libaries.
But that letter itself, they should have gone onboard with Unity since it can export to all platforms. Sure its expensive, but they are a big studio with millions of $ in revenue, they can afford it. I mean its just silly to keep each platform on a different code base when there's clearly functional options.
Look at Hearthstone from Blizzard. Built with Unity. On PC/MAC, iOS & Android.
