I have the base Battlelore game, and haven't exhausted it yet, as 10 scenarios provides plenty of action. However, at some point I will probably want to get an expansion. One thing I noticed: the expansions typically come with only a handful of new scenarios. Does this mean I can use a particular expansion with only those scenarios, or were the expansions designed with the intent that we would create our own scenarios? Seems like a bit of a waste to buy an expansion for only a handful of new scenarios, unless they are backwards compatible (that is, all expansions can be played with the original 10 base scenarios).
