I'm not asking which games which are part of a series do you own the most installments of, i.e. if you have every Final Fantasy game, but rather what single title(s) do you own the most versions of.

For example, I have Columns for the:

  1. Coleco Sonic 20-in-1 Handheld
  2. Game Gear
  3. Game Gear (Japanese version)
  4. Genesis
  5. PS2 (SEGA Classics Collection)
  6. PS2 (SEGA Genesis Collection)
  7. PSP (SEGA Genesis Collection)
  8. SEGA CD (SEGA Classics compilation disc)
  9. SEGA Master System
  10. XBOX360 (Sonic's Ultimate Genesis Collection)



I'm not sure if I have more versions of this game floating around, but I wouldn't be surprised at all. I also doubt that Columns is the game I have the most versions of. I just used it as the first example I could think of. I'll have to really think about what the most prolific title in my collection is. What about you guys?
