NN, it's not that I want to deny the merit of a good beginning to "sell" your game to potential customers, reviewers etc. But I was specifically talking about sequels. I just think that it was good pratice to make tutorials separate, optional affairs, especially in a sequel. Of course, if you change core rules or mechanics as severely as it may have been done in AoD, then maybe that argument is moot. I just wonder if it is really necessary to make every entry into a series completely "open" to newcomers.
This also goes for exposition. The typical trilogies of Films and movies expect you to go through them in series too, don't they? Sure, by all means throw in a tutorial and an (maybe optional) "what happened so far" ("cue star wars music and text scrolling into the infinity of space"), but spare me introducing every old friend as if I have a sever case of Alzheimers. I spent 80 f*ing hours with these guys already! Ease the player into whats new with the plot and mechanics of this installment - that should be the focus. If you have so many "old" players, you may do yourself a disservice tailoring the game mostly with "new" players in mind.
