I already had an inventory of board games on Board game geek, now I am trying to make my inventory of RPG and Video games. The biggest problem with the RPG and Video games is that I have more previously owned games than currently owned games. So I need to search in my memory what did I own. Some games might be added as my memory gets refreshed.
The board game collection is more accurate because when I started playing euro game, I subscribed to board game geek not long after and I registered my collection. There are a few games that I left at my parent's house that are considered as previously owned, but they could eventually get owned again. The only thing missing from my collection might be some games that I had when I was a kid.
Most of my RPG books were given or sold when I stopped playing RPG. I don't regret it too much besides the fact that some of them could have been a good source of information for board game design. Still, most of those books are still available electronically.
These are my list of video games, unfortunately, I lost of lot of games because I sold them. I thought that I did not need them anymore if I did not play enought with it. Big error for me. I remember selling Legend of Zelda for 2$ and today the cartridge is sold almost 100$. Considering that I have many game copies for PSX and PC, I will exclude any non-original CD from the list.
