I don't play Nintendo games for their story.
Nintendo games tend to have the most polished and well-thought out gameplay out there. This is a general consensus, if you have problems then it's clearly on your end.

Nintendo game graphics are limited by their console(which have been behind the other consoles this generation), but that hasn't stopped them from pushing out beautiful games. If you mean low quality by polycount, it just shows that you're a typical graphics ***** that worries about how many polygons are on the screen at once, regardless of how grey, brown, boring and bloomed they are. Also, what graphical errors?

Would you like to slip one of these on your face to catch all the **** you're spewing out?

Also, Nintendo games are far and few between, at least the ones anyone cares about. Zelda games tend to have a 5+ year gap between the next, and the games will be scrapped and started over no matter how far the progress is if Miyamoto doesn't like the game. Sure, they might milk the franchise for their titles, but the actual games are hardly milked.

As long as there are games like CoD or any sports game pushing out a new title every year at full price with minimal change(not to mention the DLC at $15 a pop for a few levels), Nintendo is the least of anyones worries about rushing titles.
