The most fun part is to plan the Character itself, as in - background, personality, motivations, aspirations. Then selecting a class that would fit. And then trying to stick with it throughout the game, making choices that the Character would’ve made, not the player.
AH yes, thank you ladydub, how could I forget this!! This really will be what'll make up a lot of the fun for me, as it is a DnD game. I'll be sure to keep this in mind when I finally play!
