I've been on t he fence about buying Mansions for awhile now and one of the major factors holding me back is replayability... as i understand it from reading the rules there are variations to each scenario but for those who have had the game awhile do the missions get stale fast? Will being the "DM" make it so that I couldn't enjoy being the investigators at some point?... the game still looks like a lot of fun and i'm sure even just playing through the scenarios once is a hell of a time but i pretty much play with the same play group so I don't want things to get old too fast.
Also a few other questions:
How are the quality of the Print On Demand expansions? Is the price worth the scenarios?
Also is it possible for FFG to add more variations to existing scenarios?
Thanks for any input.
