Wait, are you playing yourself as you would be if you grew up in Skyrim or as you would be if you suddenly woke up in the back of a wagon with partial amnesia?
In the former, it would make perfect sense to use potions and all technology of the day. Plus, you would have a different view about the types of people you would interact with as you would be used to certain personalities and hygiene levels in the area. In the latter, it gets problematic when you consider your level of physical fitness, experience with weapons, ability to fight monsters, etc.
If I was playing myself, I would definitely be a mage. And I would use potions, scrolls, and anything else that represents the technology of the world. I'd have to turn run off. I'm not going to go jogging off down the road. Too tiring.
I would also turn off the UI. It makes combat rough, but the game is extra immersive.
Both files played from as if I arrived to Skyrim. The game starts that way, so I abide by it. However, I have differing back stories why my characters end up the way they do.
First file is myself IRL. I come to Skyrim for a new life because Cyrodiil is too ravaged by war to make a living, I come North, to the lands I was born in to meet my old family and start a new life.
My second file is my son, or second character. He comes North looking for his father. His mother told him his father came North looking for Skooma, mead and cheap women. It wasn't until my "son" came of age, that a significant other found the truth. Father came North looking for a new life. Whether or not he actually "left" mother is a mystery, a mystery this one is determined to figure out.
The IRL roleplay basically takes over from there. I do what I can, IRL. That is, I can swing a sword if I NEED to, I am really good at sneaking and I know how to talk to people, even if I do not enjoy doing it.
If you, IRL, are very astute with common technology, by all means, use them in game. It only makes sense.
Just do not tell me you are using them because," Otherwise you will not get "far"."
Turning off UI is... amazing. I always thought I would need an obvious health bar. But turns out I don't.
I love it. You can never be too careful.
Just try it. Roleplay or not. Play a few minutes with no HUD. See how it turns out for you.
