From my understanding (and I could be very wrong here) is that Gone was not at as much of a completed state as Letters Kingdom.
It takes a long time to get a game fully polished, bug free, and looking nice. Some people can manage to do this in a shorter time than others, or at least to a state with less bugs.
I haven't had the chance to play either game, but from what I've gathered from the Showcase threads of each game, LK didn't seem to have as many issues with bugs as I recalled Gone did. (Or maybe I am thinking of a different game, feel free to correct me here
)

Dude, I'd rather be declared a dbpro noob than an fpsc legend any day!
