I think it would be enough to describe them on the same page. Side note: I don't think we should describe games or events to much if they have not aldready taken place. --Petter Karlsson 13:40, 22 April 2012 (CEST)
I agree on that - now I'm thinking for the archive - like the different runs of [[En Stilla Middag med Familjen]] for example. Or different Hamlet larps? If there is significant differences, just make another article. That's good enough for Wikipedia, right?
