I used to collect retro games, but having 30 different consoles/computers and a good collection of games for each was just impractical once I got married, so I relunctantly let them go to people who would have as much enjoyment from them as I did.
All I really have left is my Sonic collection, this includes a a S&K mouse mat and the 15th anniversary statue and 10th anniversary SA2, but I'm considering selling these now too.
the last time I really put some time into games in one go was Disgaea 4, hitting 50 hours after a week (!) because I had time off work, wife was away and all of my responsibilities had been taken care of, it'll be a long ass time before I do anything like that again (maybe when I'm in a nursing home telling youngsters stories of how I was a veteran of the console wars, every one of them).
