They claim there is nothing about Go that makes it bad for games, but there certainly is. There are no large, mature game engines for it. If someone was hiring me to write a basic mobile game I could do with a big engine like Cocos2D, and said I couldn't use the engine, I'd probably multiply my time estimate by five. I've written complex OpenGL ES games from the ground up before, and its a long slog, especially at the end where you you are trying to crank it up to 60 FPS and doing tons of work rewriting it to be high performance.
