I know you don't get my edition fatigue complaints, but this is a good example of why I have them. I remember being thrilled by ideas, sifting through those monster books - and coming up with spontaneous dungeon generation to make all that happen. Then I got another edition and swapped books and then another and another. I don't miss my 3.0 books - but they'd be handy to have now, and I have all these 4E books that are doing me no favors - probably you just hold on to all your books (if you had to move every year for 6 years, you would not.) and can't get my dismay - but damn I don't want to buy up new books or think about what to do with my old books! I want to have my monster books on hand.

Really those are the ones that survive usefully between systems and editions, but when you're selling them off you always have to do a big box a ta time to get credit for the next edition... Whine.

Also it's funny that you finally played an elder scrolls game and figured out the dwemer ruins connection.
