Sacred Haven of Debauchery

I think it's pretty good. For example, in System Shock or Thief, I feel completely immersed in the character and the atmosphere is incredible. I wish everyone could experience that. There were times when I felt like entire brick factories were being built as I fought my way through disgusting insects, spiders, and ship compartments overgrown with biomass, or when I was creeping through a monastery, hiding in a corner from a terrifyingly screaming zombie, clutching the last vial of holy water in my trembling, sweaty hand.
But when a game like TES forces you to spend all your mana on healing, then go to sleep to regenerate it, then hold down a button again, then go to sleep again – that doesn't really help with immersion, does it? Then all the other flaws start to surface: the emptiness of the world, the pointlessness of exploration, the generally flawed role-playing system, and the weak plot. Why explore dozens of copy-pasted dungeons populated by two ghosts and a skeleton, which have no history or purpose, and contain a chest with twenty arrows, a fork, and a rice sprout? I've played enough Morrowind and Oblivion to have an idea of the series, and I started playing them without any preconceived notions. It's hard to get immersed in the atmosphere when the game makes you yawn.

So, what about Gothic? Specifically, the add-on. What level should I aim for to have a comfortable experience?
