The KapCon dragon has awoken, and is searching for games for KapCon next year. If you're a regular GM, you should have already received an email. If not, we're after three-hour tabletops, ideally with pre-generated characters (we're also after ~10 - 20 player larps, but that seems well in-hand). Your game must run to time, otherwise you're cutting into people's eating, socialising, and personal comfort time.
As for what to run, the answer is "anything". Seriously, we don't care. If you want to run Macho Women With Guns, or a tense Call of Cthulhu scenario, or a classic D&D dungeon bash, or even (shudder) Spawn of Fashan (look it up), go ahead. The market will decide. All we ask is that you tell people up-front what they're in for (so, adult content, trigger warnings etc) so they can make an informed choice on whether to play. If you're looking for inspiration, there's a thread on NZRaG called "What games do you want to see at KapCon 22?" which lists some stuff that people want to see.
No, you don't need to write the scenario yourself (but many do). Its quite OK to run something prewritten (hell, I do that every year).
Once you've decided to run a game, fill out the form here (that's right, the one in the sidebar marked "Run a Game!")
"What's in it for me", you ask? Fame, fortune, the esteem of your peers and players. Yes, yes, OK, we also have discounted entry for anyone running a game. And more importantly, GM picks, so you can gain guaranteed entry into another game (KapCon only pre-registers the first two rounds, so this lets you sign up for that hot game in round 5 before anyone else).
With six (now 6.5) sessions of gaming to fill, and about 6 people per group, on average everyone needs to run a session. So please step up and do your bit to make KapCon a success.
