When John Carmack first put the idea of Wolfenstein 3D to the (fledgling) gaming community way back when (1990 wasn't it) people laughed at him, and said that people wouldn't be interested in running around a maze shooting things, with no puzzles. Thankfully he ignored them, and spawned the most popular genre of gaming, both multi- and single-player, that the industry has seen so far. Every game he's released (including Commander Keen) has changed the way that people write games. Every engine he's written has been a greater hit than the last, sometimes going againt the grain of what people believe makes a good game.
And the important thing is this: He hasn't screwed it up yet.
With a history thats as distinguished as his/theirs, I think we can afford them a little faith - I JC says it's a good idea, then it's a good idea. Personally I'm glad the crouch is in there, but that's probobly because, like everone else, there are times I'm reluctant to let go of the familiar.
q[dont take stuff out just because you're to lasy to code/implement it.]
Actually in programming it's refered to as 'elegent', not lazy :-P But regardless, John Carmack is a great programmer - a large part of his life is dedicated to coding. When it comes to his code, he could NEVER be called lazy.
I think thats enough ranting/rambling for one day, but I'll leave you with this: If John Carmack DID decide to remove the move keys, he'd replace them with something far superior. And you'd all love it and wonder how you coped with anything different before....
