What would you put in a Guild Wars 2 Hall of Monuments?

I'd make it cover a few different kinds of progress: completing story chapters, finishing exploration goals, and collecting things like miniatures. That way it could reflect more than one play style, instead of being mostly a checklist of expensive items.

Legendary crafting seems like a fitting category, but I’d treat it as one optional path rather than a requirement for everyone. A collection or achievement for working toward a legendary could count too, so the system could recognize progress without requiring a finished item.

I’d use tiered goals for the collections and story achievements. A small set of miniatures or completing part of the story could earn an early reward, with more goals for people who want to fill out the whole display. That gives the idea room to grow without making every part mandatory.
