I own literally dozens of systems--it's not feasible to collect for all of them, for several reasons (well, really just three, I guess...space, money, and time are finite ).
Indeed. And the MORE systems you collect, the less you can enjoy one single system. Just ask Bill he'll say the same thing I bet.
I wish I could pin-down the exact time and day of when I decided to collect videogames. Or what the critical mass was. When it changed from eagerly awaited trips to Sears, TurnStyle, Venture, Toys'R'Us, and Minnesota Fats - to "hey I got a library of vidyahgamez!"
And even more so when I decided to hang on to all my Apple II material come hell or high water.
It seems to be turning out (informal survey and hearsay) that 4 gaming consoles and 2, maybe 3, classic computer ecologies is the ideal sweet spot for universal enjoyment. From hoarding to collecting, from programing to playing, from displaying to ... whatever. Apparently those numbers allow you explore all those aspects and more without overload or deprivation. Enough to eliminate boredom and yet not consume your hobby time to point of dissatisfaction and annoyance. So you see there is nothing wrong with a "mediocre" collection!
And if you limit yourself like that you'll go through cycles and easily explore different aspects of the collection. I'm on a documentation kick now and have been for some time. Not that I'm hoarding papers and books. I purchased only 5 manuals this whole year so far. Must have been a year since I played a game on real hardware other than a PC. Even Apple II. Who knows what will come next?!?
