Social games: Evil to some, boon to makers
Has she ever seen something called long-term market and short-term market? Social games are just a small short-term market bubble : saturate it with minigames enough and it will burst.
Gaming companies should just set a SMALL budget for market segmentation, like how Dragon Age did with their mini Facebook game. Long term investment in the market is clearly a no-no without constant new content even for a simple game like Runescape, sure people won't have as much time to play, but they are more willing to spend that time IRL instead with minigames.
The less depth a game has, the less replayability and continued playability it will generate. And without any replays or anyone playing, it'll just go bust. These things simply come and go - and they are only great for trading, not investing in.
