For one thing, please speak for yourself... only yourself. I consider it to be a waste of time and horrible way to try and fill a game. For another thing, how is following vague or unclear directions intellectual? If the island I need to go to is northwest of me but I'm told to go northeast, what mental stimulation have I experienced? If I need to shut down the game to go to the UESP because I either am just sick of wasting (what I think of as wasting) my time or have no clue where to go next, that breaks my immersion into the game. Repetitive experiences don't do much for me other than think very little of the effort put into the related content. It's related to luck and random guesses when initial directions fail or are unclear, not mental stimulation... and I'd much rather have my mind be stimulated by content to ponder at the quest location, not repetitive landscape. Give me a puzzle or a story, but I'll pass on the tracking.
Well people's intellect level are different.
But seriously, by intellectual directions, I meant that you had to check the in-game visuals with your memory of the address given to you, so you kept looking at the scenery, and did not loose your immersion.
Just like in real life, as when you are walking around, you are looking at the scenery, not at your wrist watch for instance, all the time.
In Oblivion, I did not need to look at scenery a lot, and the compass game me all the information that I needed to reach the destination, and fast travel completed this phenomenon as well, complete lack of immersion in a game that gives you another world to explore. WTF?
The compass had another bad effect as well, as it showed you all the interesting places you had around you in a large radius. So no nice surprises when you found a new place, as in Morrowind.
That repetitive experience, kept my mind busy and forced me to use it. A lot better than repetitive experience of being nose leaded by a red or green carrot in front of my eyes.
