That's certainly a reasonable perspective but for me personally I've been through the whole "collect anything and everything" way of collecting and I found I lost enjoyment. Space and money are also issues. Sure there might be some interesting precrash systems that I'd love to find and at least try but I simply have no place to put all of these. I already downsized, getting rid of those systems I played the least or not at all which included N64, PS1, Dreamcast, Intellivision, ZX Spectrum, Commodore Vic-20 and others I can recall at the moment.
If someone has the time and desire to "collect it all" I think that's fantastic but I don't like the idea that if someone doesn't like, play or collect for certain consoles then they are somehow less of a collector.
