Some friends and I have just started playing Arkham Horror and we're starting to dabble in expansions. The big-box ones are nice because they add some variety to the available investigators, though it seems like the extra boards are usually an exile for someone to go and do busy work (closing rifts in Kingsport, for example). That's another topic, however.
Branding all the cards with the expansion logo makes sense so you can pick and choose which expansions you want to have active in your game. Yet, the monster tokens aren't labeled. Is there a reason for this beyond "monsters are monsters, just leave them in"?
How do other players and groups handle this? Do most of y'all tend to use all the monsters from all expansions every time, or do you go through inventories and sort them out the hard way?
