I would say bad engineering:

* Go 1.0 had a terrible GC, especially on 32-bit platforms (their target platform)

* No manual memoray management (and unlikely to ever exist)

* Can't bind to C++, can't cross-compile cgo (gccgo can though)

Go is really cool, and I use it every day, but it doesn't make any sense for games, especially not for their target platform. Maybe in a few years the GC will be more reliable, but I wouldn't try to build a game in Go if I thought I might want to try to sell it.
