The one thing that made my start in EVE diabolical was no manual or guide outside of the game.
No matter what type of in-game tutorial system you have there needs to be out-of-game manual.
The best example I can give of this is: EVE only. Or EVE in conjuction with ISK 3.0 (ISKtheguide.com).
My first foray into EVE meet with failure because I just didn't understand what to do, or the setting. A year later, after unsubbing, I came across a reference to ISK 3.0 and purely on the strength of the clear layout and explanations in that guide I chose to resub and am loving EVE now.
