let me clarify that a large portion of this is out and out collectionism and not "Gonna sit and play all these" - though i did make a dent into number of games played through to about 2004, life slowly took over and it -was- literally about collecting. I'm not making any bones about that.
It was a fun hobby to be honest - i lost money overall, but with some of the arcade boards and a few of the rarer games i made a pretty sizable profit. Still - it was excess - and ultimately the need for more space for the kids trumps being able to play native RGB retro games. That's obviously going to trump emulated options any day of the week, but the reality is my laptop/t100 has pretty much every game i owned retro wise and a ton of the PS2/GC/Wii ones and i no longer need to dedicate a huge chunk of space to it.
That said - if you ever woke up and thought "i just fancy trying something weird" or "i just fancy playing <game>" - chances are it was on the shelf - and that was a nice to have, but little more than that.
