When production costs became too high, in order to make a game these days its going to cost over 20 million.
Just look at how many publishers there was 10 years ago and look at how many there are now, the game industry is concentrated into main groups that just want to make a profit.
They are still some visionary people that are allowed to make their games as they want, like Hideo Kojima, but such people are rare these days since publishers want to rush out games as fast as they can so they can get a return of investment, the problem is they are afraid of inovative ideas and go into the "tried-and-tested" concepts that makes their games just another title in the market with no appeal.

Sounds like the movie industry, sad but true. Despite the community critizism about the rushed ending of TSL, Lucasarts don't have a reason to pay attention to the enthusiasts within the gaming community. TSL sold 500000 copies on the xbox in the US in december, and it's currently #1 in the UK, even selling more copies than World of Warcraft(probably due to it being multi-platform game).
