My vote also goes to CKII, it's not like they didn't try but I guess developers should just ship tutorials as videos with the game. That's pretty much what I do anyway on most grand strategy or management titles: go to youtube and look for some guide or let's play that explains what's going on.
Also X3. I didn't understand how to get past the tutorial, so... I uninstalled.
Freespace 2 had very boring tutorials that had really good information .. and they sweetened the deal by giving you a medal for putting up with them. And I liked how they gave more advanced lessons as you progressed in the game and explained it by being assigned to another squad. I just love that game and everything it did.
Racing games played from third-person - it's just cheating, in my book - it also makes it harder to control the car because by the time you see it sliding, you should already have corrected it!!
I tend to stick with bonnet-cams because in-car shows far-too-much dash/pillars etc. Yes, I can see those in my real car if I LOOK at them - but mostly I just see out of the windscreen. Developers need to consider that - they need to remember your screen is set away from you, not in your chest!!
At least one of the Shift games does just that and gives a 'zoomed' option from in-car - but games like Dirt (2 onwards) use the in-car view as a difficulty setting, with achievements and rewards boosted for using it!!

I keep forgetting X3 has a story. I bought it, selected the custom start, then attempted to conquer the universe. No tutorial to worry about. Much nicer. That fucking interface though. I can only handle playing the game for a couple of weeks at a time before the constant going in and out of the huge nests of menus starts to drive me insane.
If I remember rightly, I've got huge sprawling bases in all of the main pirate sectors in the middle of the galaxy, with patrols guarding all of the gates.
Damn, I'm starting to get the urge to play ...
They had the challenge modes to help teach some fundamentals for multiplayer. They are trying that again in the expansion with more multiplayer tutorial missions.
