Honestly I didn't look into the menu's that much, Having to use the keyboard to navigate some menu's and the mouse to do other turned me off from trying to search through for different options. Was also having too much fun playing the game to play with the menus.
I don't mind the STA, END, INT and limited stats... it's the putting the points into perks(I used the wrong word before) that's annoying. Knowing you have a limit to them vs giving you a huge array and not telling you anything was just annoying.
Maybe it's because I have not played the other elder scrolls games, but having the right hand bound to left mouse button just makes no sense. I mean it's purely a graphical thing, but when you have two big things readied on screen it seems to me most people will click the left button to activate the left object on screen. Best example is I have a giant shield out in my left hand so i'm trying to click a new sword I'll hit the right button because it should go on the right side of the screen, not replace the left item. I think the reason they have it that way is like you said about a primary button for use, but then it comes down to them discriminating vs left handed people. Guess i'll dig into the menus.
Still vastly enjoying the game vs others of simular fair.
