So I've never really bothered with the option to watch a video for free glu credits because I figured it might give you like 1 and then that's it, but I've played like 10 videos now and each one has awarded me another credit. Is there any limit to how many credits you can get doing this? If it's unlimited, had I known, I would have done this right away at the beginning of the game! I'm just at the end now dangit!
I think there is a 20 video limit for some games (though I'm not sure about HOD, specifically).
