One episode per week is fine. They can be a little bit longer if there's a natural conclusion after 2,5 hours or so. But I have enough of a hard time trying to keep up to date with all the GB content as it is, so I don't really crave for more.
I'll play a Mortal Kombat or Street Fighter once in a while, sure. But it's not my favorite genre by any stretch and I will admit that the wealth of fighting game content coming from GB West has made me pay less attention to their content.
