Its funny how you guys create new stuff before giving old stuff a purpose.
Notch: Let's add mushroom cows!
Jeb: What about adding uses for Enderpearls?
Notch: Screw Endermen! Lets make Nether Dungeons!
Jeb: What about the exp bar...?
Notch: Jeb, shut up, I just wanna insert things and never fix the bugs in a previous update!
Please don't post topics like these until 1.9 is released, I normally enjoy how funny these rage threads are, but really, there are so many all about the same thing that now it's just getting frustrating.
Notch is lucky that he owns his own development company. Anywhere else his magpie like development style would just get him fired.
I know exactly what it feels like working on the same exact thing for several years. Its really tough not to want to constantly go off and do new and fresh things. However, if you fall in to that trap all you are left with is a string of half finished projects. Which, minecraft has basically always been.
Sure the game is fun, but imagine how much more fun if things were finished.
