I mean, it's a 22 year old game, but since you asked nicely... 🤷♂️
Seeing that silt strider just outside Seyda Neen after the intro to what looked like your run of the mill D&D style fantasy RPG was a surprise, to say the least...
... and it was just the beginning.
It's a real shame later Elder Scrolls games mostly lost that otherworldly feel.
It's almost impossible to have not been bombarded with the main story and setting of Morrowind by this point. But when this game came out, it was an experience and a half. Unlike anything I had seen before at least. Sure, Ultima, TES 2, etc all existed. But none of them had never sold their world so effectively if you ask me.
