I'm really looking forward to adventure in a world where my actions have consequences, and I can stand up to evil and beat it flat (3 most satisfying moments in BG3:
Beating Auntie Ethel the first time, saving Isobel, and then beating Auntie Ethel again
)

It's not just about beating difficult encounters: It's about standing up to the bad guys when you could have just walked away (and they even try to bribe or induce you into doing so).
