I like to look at it from a game design decision of what tools you are given.
It's been discussed in other games, but everybody, seriously everybody, is going to find the most efficient way to get from point A to point B. You can give somebody a million different button combinations, but if pressing X over and over again is the quickest way to go about winning a fight, why use the other tools? They're superfluous and don't really enhance the experience when unneeded. Why waste the time putting in a tonne of options if one easy solution trumps everything?
What's really good design in a game like Fallout, BG, or D:OS is that the system is designed in a way to go around this, giving legit multiple ways to complete a task that are all equally effective while not having a single option that is just flat out unfun. Stressing out about min maxing in this game is quite silly as there is no top tier solution (although pouring all your points into loremaster and telekinesis might not be the best way to go about things). Sure, you can rock out 2H, but you have a whole plethora of options that are as viable and don't ever make you feel like you have to do something one way to really blast through a scenario. There is no quantifiable "best" way to play the game, where as other recent titles surly have that problem.
Hell, we've got people on all ends of the spectrum saying what's the "best" way to go about the game, but nobody really has said "X way of playing is the only way to go." All your options are fun and any way you want to go about playing is going to get you to the end without you feel like you've wasted your time.
People will tear my head off and it's something I didn't want to believe myself, but I really think there is nothing in the world that wants to make me play a game less than clicking on a spot, watching my characters move there, then clicking on another spot, watching them move there, and so on for hours on end as I move back and forth in and out of an ugly, dull town. Such a flaccid stop-go method of interactivity and feedback wears down my enthusiasm. Olde style CRPGs have become very demanding of me. I'd probably get over it easier if the setting and characters weren't so plain and trite.
Well, you can hold the mouse button down to continue moving in one direction? I'm not entirely sure I understand the complaint.
Also, I'm not really understanding the "plain and trite" issue you have with the setting. The world and characters are fantastic to interact with.
