At first I was going to argue that the Shadowrun stuff isn't confusing (SRM being a Shadowrun Mission and CMP being a convention special with everything else either a tournament, LARP, or beginner intro but you can actually bring a Missions character into the LARP and beginner games, and there is that whole separate seasons thing, but it would still be nice, imo, to separate out those pesky Living adventures from the rest.
In addendum, I both play AND run D&D and I find determining those difficult too. There are regions and Epics and that thing I think of as Ravenloft, and Ashes of Ashas(which I miss) and bringing someone new, yes, absolutely stark raving never-before-played-an-actual-rpg new into a living campaign can be so tricky!
(We are, btw, bringing one of those folks this year. They do exist. He has never played an rpg except via a computer game, ie Elder Scrolls, and has never been to a con or a FLGS. I...can't wait. He's either going to realize why his life was so empty before or he's going to think we're all crazy. One or the other. :D He's getting assigned a 'gencon buddy' to pick events to do together and be joined at the hip with, trying a little of everything from rpg's to mini painting and mmmmaybe a LARP. We showed him last years events and he was utterly unable to search for anything. Dividing things up for him is pointless, he has no clue what he's looking for.
However, NEXT year, assuming he gets addicted, different categories other than glopping them all in RPG would be grand. I do wish the things were easier to sort. Like, if we could have tags. So you could click...horror, nonliving, beginner, rpg, no materials necessary, 6pm to midnight start time. Go.
