Instead of a new board expansion with new rules and mechanics how about a "big" box expansion that adds to what there already is.
Things like the errata for investigators and items , ect.
Add more items , uniques , monsters , AOs , investigators , mythos , ect.
Plus maybe some more tokens like the gates that have different negatives numbers for closing or even dual monster symbols.
Then more health , money , ect tokens would be nice.
Just a thought. ![]()
