Please share your best moments here, I'd really like to read them, here are some of mines.
Three things that made me happy during the gameplay (there were much more):
1. Feeding the lone woolf near Fort Monastery in Avernum 4
2. Obtaining Reproducing Bulwark in Avadon 1 which spawned bricks in your inventory during combat (meant you were s***ing bricks - "Pop!")
3. Love story in Avadon 2
I also loved having my houses in Avadon 2 cause I could put all my inventory trash there.
And defeating a god in Avadon 2 for achievement "A hand fears nothing" which gave me the chills and goosebumps.
