It's interesting to see the differences in collections. So far, NES is a huge part of a lot of them. It's surprising for me, because I only have about 12 NES games, while most of my collection is devoted to the precursor age of Intelly, Coleco and Atari.
Anyone who feels that they don't have a HUGE collection yet, there are drawbacks too, you know. Such as physical problems due to space, possible complaints from any spouse / long-term partner, and insurance issues and a possible Ebay addiction. So, it isn't all that bad.
