It is not exactly like BG. You do not have the ability to set formations for the party and lack some commands like BG's Guard Mode where you could set a party member to attack anyone in a predefined area but not move outside that area (or at least if does offer such features I was not able to find them). And to say that everything is simple after one has figured out what all the confusing options actually do and how to set them in a way that complements one's playstyle is rather like describing a riddle or puzzle as easy because it will be once one knows the answer, which is true in a sense but not what most people would mean by describing a riddle as easy.
Now you're arguing just to argue. These are nothing like riddles, whose purpose is to figure them out alone, rather than information freely given in the bloody manual and all over the NWN2 forums, or from anyone online who plays it if you can't be bothered to look for those. I'm sorry you find it so all-fired confusing and puzzling, or that you're so determined to do so. Help is there for anyone who needs it.
Also, you should know very well that setting formations and guard mode aren't what I was talking about when I said it was exactly like BG -- I was referring to taking control of the companions, accessing inventory, and all of the other things I listed in my previous post.
By all means, go on your merry way believing that it's so hard to use and simultaneously overcomplicated and not having enough features. For anyone else, if you're actually interested in playing and find anything about the companions confusing or difficult, after having read the manual and explored the in-game options, ask in the help subforum and I or any number of other helpful people will be glad to help.
