Zenith said:remove the multi-platform games. then there's the fact that I personally don't like racing or multiplayer-orientated games or Ratchet and Clank. that leaves Uncharted, Ninja Gaiden, Heavenly Sword and Resistance. all great games I would love to own but it's not worth getting another console. I can go without, especially as there so many other non-exclusive games to take my mind off it.
It's a ridiculous argument: If I were a PS3 only gamer thinking about getting 360, your logical fallacy would also lead to the conclusion that the 360 has no games compared to the PS3. Most of those games are currently on the PS3 as well and if you discount titles from genres you dislike you can also conclude it's not worth getting the 360 for just Halo and Bioshock.
