I have eighteen total consoles and the one that gets the most, "Awe" is probably the Virtual Boy. The 3DO gets good looks as someone once called it a Beta Player.
I thought the Neo Geo Pocket Color would get more reaction but it just sets there, not to really wow anyone. The Jaguar is one of those, "I heard of it but never seen it" type of deals and the Lynx is about the same. Some people cannot believe I spend money on certain consoles.
I have nothing too obscure, most of my hardcore gaming buddies have at least heard of all the consoles I have (save the Neo Geo Pocket Color) so thee only thing that really makes anything weird is that I actually spent money to own one.
