tutorials: the problem with stand alone DLC

I finally got around to paying Freedom Cry, which was one of the free "games" one PS+ recently. I ended up giving up pretty quickly, since I could not figure out combat in the opening sequence. that's when I realized: it didn't bother with a step by step tutorial because it was DLC; not an actual game.

which brings me to my point

creating stand alone DLC raises some huge problems with tutorials. on one hand, people who bought it as a DLC don't want to sit through what amounts to a tutorial of stuff they've already been told by the game earlier on. however, people who bought it as stand alone won't know any of the controls without such a tutorial.

what do you guys think is the solution here?

I mean, this is a problem that already existed when coming back to a game after a long time of playing other games, but the stand alone DLC thing just amplifies it.
