Though I kind of prefer "immortal mode" (Skyrim and Fallout 4's "tim" command), and just kind of use it as a crutch.

Yep, that is how she plays too. Mostly because, like I said, she cares more about lore, story, and characters. So she makes herself immortal so she can just wade through any challenge and not have her story disrupted.

On that note, we also fight very differently. Since she has infinite ammo (because of said commands) and is blind as a bat without her glasses (she doesnt wear them while playing), she has a tendency to use melee weapons, and if she uses ranged weapons its AOE like grenade launchers, or bullet hoses like miniguns, and she will go into battle screaming "ACCURACY IS FOR DOOOORRRKKKS!!" at the top of her lungs. Meanwhile, I favor custom-tuning my weapons to make them as accurate and easily controlled on the recoil as possible, and when using anything automatic I fire correctly in short controlled burst. Or in Elder Scrolls, she prefers magic, while I prefer heavy armor/heavy weapon+bow builds.
