Wonder if its even possible for this guild to have a turn around and become active once more.
Quite possible, but it would take a concerted effort by more than a handful of people to get tournaments, games, discussion going again.
I'm lacking in the game department at the moment due to crappy job and selling my ds and 3ds, so I can't help give out prizes or setup tournaments with rewards within the game(s) themselves, but Gaia money pots, items and the like are possible.
Forum discussion - be it just chatting, roleplaying or whatever is still possible and only died off a few months ago and degenerated into spam that I was deleting. Those within the guild, if there is enough interest in it, I'll pop open the sub-forums for and let some people tear into them to get stuff setup.
