Bit of backstory - I recently went to Japan, mainly to vacation around but also to get some new games (retro ones). When I came home I wondered what my collection is worth. Eventually I got round to indexing everything and my collection came to around 6000 USD. I have around 250 titles. Mainly for PS2, 3 and 4.
So I was wondering if we have anyone else who has done this or would like to. It's fairly easy, quite fun and helps to just keep track of things if you are unsure what you already have as you can save your collection!
