Well alignment is one thing, but I mean you have to choose one character - one role xD
For someone as indecisive as me, it's the hardest challenge.
And even when you have a character you just don't find that inspiration to give it that touch it needs to feel great.
Can be a trial and error thing, but it's really fun, I highly recomend just giving it a shot, and ask for opinions and thoughts from the host (AL in this case)
