I just wanted to share a video game collecting resource with AGD. Pricecharting.com is amazing. They have line graphs of value of certain games over time, ebay tools, lot value calculators, and more. I love the site and recently found it a few months ago felt I would post it here for any that were curious.
Its interesting to see what games are going in value the most quickly (Sega CD and NES are both good from investment standpoint according to the line graphs.) www.pricecharting.com
