He explained it with rage. When they showed rage on QuakeCon everyone expected it to be much like Borderlands or Fallout although that has never been their intention.
They don't show doom to cause wrong presumptions or expections, apparently.
people will still judge and compare upon release. it's irrelevant of time. Carmack also said something how they're gonna go "BETHESDA MODE" will Doom 4 and then made some cheesey food analogy (no pun intended) which basically said you'll see the game when it comes out.
what? rage was clearly tried to be a fallout/borderlands ripoff on a good engine. it just the engine wasnt 5 years ahead of time neither the game lived up to those titles so it flopped.
no. the engine isn't so good and they did a poor job at it. hardware is light years more advanced than it was when quake 2 or 3 came out. developers are just bad at programming and at using hardware to the fullest.
there were more complex games on C64 in the 80's than some are today.
There's something really refreshing about how self-depreciating his outlook is on the games he has created. It's not some bloated self promotion, it's one of a kind in the sense that he's being honest with gamers about his team, the arc his development takes, and his own thought processes. I'm going through it now and it's just really cool once you set aside the rage you feel for missing like, all of the games in the quarter and semi-finals.
