Hi from Germany,all four games are worth having them. Combine them and customize them.
Just four examples:
Add your own adventurers and do not limit yourself to dungeons.
Expand the sequence of play to get rid of the mechanistic, simple process with far too easy predictable results.
Add content drama to each adventure.
Create real parties with companions, henchmen, friends, etc. The game system carries all of this and more.
Cheers
