@YourDarkPriestLong time no see!
1. I'm good with Discord for the smaller moments, yeah, but I'd always prefer the forum.
2. Any and all, I can make it work. I'm particularly in to the Warhammer 40,000 universe right now, and can supply the neccesary PDFs for the universe.
3. Roleplaying is a must for me, I'm always pulled in to personal plots that focus on the players and the consequences of their actions, especially if the mechanics would rather have you just move on (combat in D&D explores this) after a battle. I'm all for crime, and politics are particularly neat.
4. I'd love a mix of NPCs that would be able to travel with us according to the plot, or would require us to care for them to keep them alive. It's through these experiences that even the smallest Imp can be more important to the players then the big bad. Camaraderie is a must, along with keeping these NPCs semi-useful to encourage player interactivity and a reason to keep them around.
5. I've always enjoyed smaller.
6. Homebrew is nice if it doesn't unbalance everything and instead adds to the experience.
