I agree broadly with the point, and I actually think this points to another place that careful design can improve immersion. I've been talking about decreasing the distance between player/character decision making, but that actually goes both ways. If you're playing a thief type character, that character may generally prefer to use stealth as a strategy, because they believe themselves to be good at it. If the game is well designed to increase immersion, then that is likely to be a good strategy for that kind of character, that you might also prefer as a player.That's a great point, and I completely agree. System mastery does indeed, IMO, make immersion easier.
If there's little room between player/character decision making, it actually doesn't matter if you opt for a given action because it's effective mechanically, or because it's a skill the character believes themselves to be good at. The map and the territory are very nearly the same thing.
