I understand that a more fluent storyline is yet to come. But can someone give me an idea of what the overall story is? I'm just not picking it up.
Gary is a new game master, and he's really obsessed with this game his older brother Melvin is playing. Melvin thinks Gary is a scrub and they have some sort of conflict over how hardcore you really should be as a gm. I guess it's a classical success story where Gary proves himself?
Ok. And in terms of the missions, is there some overall goal the (player's) party is trying to reach?
There's currently no overall campaign story no. Currently you're basically running various modules rather than a big fantasy campaign.
