The Girl and I moved into our current house just under a year ago. Some of our initial choices in where to put things have never been fully satisfactory. Yesterday, we began implementing a plan we’ve been discussing over the past couple of weeks.
The RPG library – which occupies approximately 60 shelf-feet of space – was previously sorted alphabetically. As part of a larger furniture rearrangement, it is now arranged by genre. This is still not entirely what I’d like, but three-dimensional bookshelves only support usable organizational schemes in two dimensions and are wholly unsuited to a rapidly-searchable multi-attribute tagging system.
Still, it’s probably more rational than sorting 40 years of RPG accumulation autobiographically.

I’ll go you one better. Sort them by order of preference, and take turns. I’ll bring the popcorn.
Jeez. I’d have decision paralysis for days. Am I judging on system? Setting? Aesthetics? Vibes? Friendships acquired over the course of play?
Yes.
