I sold off some of my books before, ones that I hadn't used or even looked at in a while.
I regret it so hard.
Ignoring the sentimental aspects (which is significant for me), if I decide I want them back I now have to pay probably double or more what I sold them for.
I will probably never sell anything again unless I have multiples of it.
I am a big fan of Iron Kingdoms, which is steampunk fantasy (somewhat similar to Victoriana in that way, though it often bleeds over into dieselpunk). The game is not very easy on the GM though, so I use Savage Worlds to run it. While it may be a stretch to call Deadlands "steampunk", the rules do handle steampunk really well.
