You're enabling awful business practices by publishers to push shit out the door.
The only two games I'm seriously looking forward to are Metal Gear Solid V The Phantom Pain and Street Fighter V.
Both of which I'm guessing won't have these problems. I don't know why Japanese devs aren't having these problems but western ones are.
I'm looking forward to Fallout 4 and Uncharted A Thief's End.
I've enjoyed the Fallout series plus this one is set in Boston, the area where I live. Pre-ordering is the only way that you can get special editions (i.e. the Pip-Boy edition being released this week). That being said, the Fallout games tend to have a lot of bugs on first release. Whether this is related to pre-ordering or not is still up in the air. I agree that there is likely more business pressure to release a game on time, no matter what condition, if you have customers that have already paid for the product. But I'm not sure that other business pressures wouldn't cause the same result (i.e. pressure from marketing, sales, etc.).
Uncharted has been delayed to spring 2016 to continue polishing the game. Part of this was also to more closely tie in to the movie version which was scheduled for release in June 2016. However, it's an example of a game studio delaying a game to get it right. The movie version, for those interested, just lost it's director and actor so it's unlikely that the movie will be released in 2016.
Whether pre-ordering causes games to be released before they are ready or not, it's not going away. Why? For social reasons. People who pre-order want the game first for social status, so that they can play the game first, brag to their friends, and to get the limited edition versions. You can see a similar dynamic when it comes to new Apple products. Value wise, it makes sense to wait, but for some people that rush of being the first and the center of attention, even if short lived, is worth it.
