If a certain type of game needs a lot of background, and it’s not the flagship, then it might be worth considering running a different sort of game at Chimera instead. This is kind of what I mean - it’s horses for courses, some games might be better for stand-alone than a con.
Take The Ch’akta Peace Accord for example. Nick said after the game that it wasn’t intended as a convention game. It was a science fiction setting with a detailed background, and there were certainly a lot of background info and character connections that were hard to grasp through the con haze. I loved the game, it was one of my favourites. But there was a long period of note-reading for a lot of players during the game, and some people seemed a bit stressed by not feeling on top of their character and the setting. I would have enjoyed the game even more as a stand-alone, where everyone had dedicated time to study up, and more time before the game to get the hang of who was who, what species they were, who their friends and enemies were, how people fit into the background, etc. I’m not just talking about immersion, but the comfort of the players in regards to feeling on top of the game and their character. At one point I gave someone totally incorrect information because I hadn’t found time to re-read my species briefing sheet and forgotten a major aspect of them. Whereas for a game like Asterix, I didn’t get the impression that complexity was as much of an issue for players.
It’s not that I think that some games shouldn’t be run at a con at all - I’m very glad to have had a chance to play in The Ch’akta Peace Accord as I might not have otherwise. It’s just that I reckon people might want to consider con brain-melt when considering what to run during a six-game weekend, especially if writing a larp specifically for the con.
