...wish you did.
I bought a SNES Mouse, and I regret it. MARIO PAINT was fun for only a little bit, and other than that, I don't remember much being available for it. Actually, I can't think of any other titles, though maybe SimCity2000 did?
I didn't buy a SNES SuperScope...and not sure if I should have bought it or not. The thing looked super cool, but was anything really out there to make you buy it? I saw a Metal Combat (?) game today....but reviews of that and Super Scope Six didn't look too interesting. Maybe I could have used it for T2: Arcade Game, but I never bought that. ?.
I didn't buy a NES R.O.B. nor a Power Pad. I imagine if I used the Pad, I would break it, and the R.O.B. seems like a peripheral that isn't worth having around taking up space, even though I have the games for it (I think).
I didn't buy a Game Boy Camera or Printer, nor a Sega Menacer (would pick this up if I saw it).
I don't own a Dreamcast but I'm considering buying up new official controllers on clearance for $5 each. I still can't believe that Sears clearanced out Sony Dual Shock controllers at $2 a piece and I missed it.
I also never picked up the NES cleaning kits at T'R'U when they were $0.17 each
