I can agree and disagree with this thread.
Personally, I find most of the controls to be very intuitive for what they do and (once you get them muscle memorized) easy to use. It is an incredibly massive interface, with many different areas in which you can go wrong, but once you've got it, the basic stuff is pretty simple. You just have to be willing to learn as you go.
That said, there are several areas that could seriously use some polish and there are still some that are kind of clunky. This does lead to challenge, however, the challenge isn't part of the interface; it's an internal one, and that is learning to have patience do deal with things that are going to be fixed. (Very Zen if you ask me)
I will admit that this is a game that I shelved about a year ago, saying, "This is just too complex for me to grasp right now." for me it really wasn't the interface as opposed to the shear number of things required to play, but I picked it up again about a month and a half ago, and find myself simply amazed at all the things to do and learn.
One of the things I've learned is that this is an
incredibly complex game, with not really a learning curve as opposed to a learning cliff face.
* But as with the any game of this depth, I don't ever really playing without the wiki open -- so I always have ready access to whatever information I may need.
read: A learning ceiling suspended over a bottomless pit, to which you must cling or fall to certain doom. Also the ceiling is 400 feet above where the floor used to be and the floor was just knocked out beneath your feet.
But with a little time and effort, the challenge becomes an internal one, and with a little bit of drive you
can succeed.
To address the second point of the "I'm more intelligent than you because I mastered an incredibly complex interface." personality type. Some people are just dicks. It doesn't matter how you cut it, they're out there, but let's be honest, if you are playing a game of this
depth you are probably 'smarter than most' and you rightly take pride in it. I also get a sense of that with the community as a whole, and thankfully it makes me feel like I belong here.
tldr;
All told, this is not a game for the weak of heart, and somebody not used to a control scheme utilizing MOST keys on the keyboard in one form or another, will probably feel lost for a while, mastering the interface is part of your eternal challenge, and people are dicks.
Sorry to hijack the thread, but case closed.
