Chess, go, bridge, and poker, most people would agree, are among the most complex and challenging of all games. Yet the rules for each are simple and known from the beginning. Imagine trying to play chess without knowing how the pieces move. Or trying to play poker without knowing the rank of the hands. Yes, you can learn these things by playing, making mistakes, and losing over and over again. But why should you? The problem with D:OS, imho, is not that it is too hard, but that even the most basic rules--such as how to craft, to name but one--are not documented. The User Manual is so basic as to be useless, and the online tutorial is not only incomplete, but haphazard in what it covers. FAQs are now beginning to appear, but this is simply the result of Larian foisting the job of documentation onto users, who have paid good money for the "privilege." Please don't tell me stumbling blindly through the early game is good for me or that I am too lazy to die a hundred times in order to learn. I don't mind a hard game, just one where the basic rules are a mystery.
Nothing in the game is really "new" in terms of cRPGs. People who are experienced with them aren't having problems with the game. In fact, this game was designed as a spiritual successor to Ultima VII. It also is far more intro-friendly than Ultima VII was.
Anyone who takes the time to read the manual will be fairly well prepared for the game. Sure, there are things to learn on the way, but... well... that is the point of these types of games. If they could teach you everything possible in the game with a quick tutorial, why... it would be like every other shallow piece of mainstream garbage out there to which this was specifically designed to remedy.
Does that make any sense now?
