Yeah, I can understand that, but tbh with you I haven't missed physically having those games one bit. I think personally it just got to be a little too much for me to deal with all at once. Plus, school and real life in general got in the way of game time and I hadn't played most of my games in forever (that durn real life always gets in the way lol).
At one point I had over 600 games spanning something in the region of 20 systems, but now after selling what I did I am down to a "lowly" 200ish games spanning 7 systems (N64, Dreamcast, Gamecube, Wii, Xbox, Xbox 360, and PS3 w/ PS2&PS1 bc). That amount of games to me is manageable space-wise and if I ever get into a retro mood my HTPC is hooked up to my TV and I have my PS3 Street Fighter IV controller ready to go! I think it does a pretty good job of recreating the original experience. JMO of course
