Preview-less tutorials

[tuckjohn]

While I was reading the review that euro gamer recently have KSP, in which they said (in a gist) that "the tutorials should not exist as they give a glimpse of what it is like to make milestones", I thought that tutorials could be "unlockable". The idea behind this is that to unlock the tutorial on how to land on the mun, you first have to get into a stable orbit around the mun (in your career/science/sandbox save), and then you would receive a message that you unlocked the tutorial on how to land. There could b other milestones as well for other tutorials.

Anyone else have an opinion on the idea, or a way that this could be done better?

I would prefer it be more like that you have to do them in order at least once, you can't just buy the game and go straight into an orbital rendezvous tutorial.
