Quote from TaylorWestern gamers (speaking generaly here) like the triple A massive titles and little else, the sales drop dramatically after the top few.
I really see no evidence for this, if by western gamers you mean hardcore western gamers then I might be able to see that, but the average gamer in the west does not play gears or halo. The hardcore gamers that eat up the huge budget AAA console titles that pervade the game industry are actually a fraction of the wider game market.
I see a lot of game developers views of what the game market is shrink and shrink the longer they are focused on AAA development.
These studies all vary a bit, but they get the point across:

if you average all of them together I would say that gamers are around 50% women if not a little less, so right off the bat most AAA big budget games are marketing towards only half of the total game playing populace.
other stats worth quoting:
What Kind of Games Are Played Online Most Often? (ESA study)
52.0% Puzzle/Board/GameShow/Trivia/Card
7.0% Persistent Multi-Player Universe
I'm not saying that everyone should be clamoring to make Puzzle or Trivia games, but that is just an indication that the average online gamer does not play WoW. In any case, I have seen many reports stating Runescape has more players than WoW, so the AAA logic doesn't hold up there either. AAA games really cater most to hardcore gamers, and in turn - they spend a buttload on AAA games. But I do not think numerically they are the largest audience.
