Regardless of the difference in complexity, I think the fact that it became the bestselling videogame of all time despite the fact that it essentially "has no tutorial to speak of, no on-ramps for new players" makes it a valid example for showing why tutorials and on-ramps for new players are not as important as the comment I replied to made it sound.

If you disagree, I'd like to hear your thoughts on where you think the threshold in complexity is when games should start including a tutorial and/or on-ramps for new players.
