I'll start :)
I still clearly remember one particular incident. It was my first playthrough, where I didn't know what to do at all, and I've been pretty battered down. I arrived in Pelagiad while the sun was settling behind the horizon, really exhausted and close to getting killed. But just the feeling of finally going around the corner and seeing the tavern, knowing I'll be safe there, was an amazing feeling of relier. I'll hold it with me forever, and I don't think any other game managed to implement it in such a way.
What are your memories?
Finding the Path to Azura Cave. It was so dam hard but once found it has been burnt into my brain.
