From time to time I remember that I have never completed either Grandia II or Skies of Arcadia on my Dreamcast, or that Powerstone 2 is one of the BEST party games provided your TV screen is big enough considering the character scaling is almost worse than SSB:B, or all the other DC games I must have spent a small fortune on in the past 9 years or so--my IGN collection list says I have 22.
I usually plug my Genesis in to reminisce with MicroProse's Pirates! Gold (recently remade as Sid Meier's Pirates! for PC), Streets of Rage 2 & 3, or Sonic & Knuckles.
Gods, I would pay damn near ANYTHING to get Sonic 3 & Knuckles (together) for the Virtual Console.
Other than that, my wife and I keep my PS2(fat) in the bedroom so she can play her Final Fantasy games on the lazy weekends (7, 8, 9, 10, 10-2 & 12)
My Saturn unfortunately, sits unloved along with the as-yet-not-working NES I found at a thrift shop; and my two N64s for which I have only three games: Ocarina of Time, Body Harvest, and Conker's Bad Fur Day.
