Maybe it's just me, but I approach any crpg with the attitude that I'll have a couple stabs at a playthrough to learn the mechanics before making a serious attempt. The environmental/positioning stuff? I learned that when
the gnolls in front of the cave
took my ass to town. But then I knew those mechanics. Is it reasonable to expect a full understanding of every mechanic to be achieved through a tutorial? Maybe sometimes, but maybe not always. I felt like the tutorial on the ship was more than enough. Jump. Push buttons. Loot stuff. It's more than enough to get started, without getting overwhelmed, and I think not overwhelming people is preferable to scaring people off with complexity.
