I think a really good way to do a tutorial would be to have a special “tutorial NPC” (once they work and all <_< ) that assigns you missions specificically suited to getting you on your feet, walks you through improvising some of the basic weapons, some basic info about kiting and obstacles, explain how stealth works (mostly that you can see monsters before they can see you), and some early looting.
Just a thought.
To be clear, I’m not against having popup tips in the game, not sure where to put them in the interface though, we don’t exactly have loading screens.
