Hey, hopefully there's some room left, I've been itching for a good tabletop rp. I've never played 5e but I've got a lot of experience playing and GM'ing for Pathfinder so I think I can pick it up quickly.

>1. Discord or no for conversations that don't require a lot of extra writing between naritive?
I've played both ways to great lengths and enjoyed each. I have no preference.

>2. Space and aliens sci-f, High Fantasy world wide adventure, or horror, death, and suspense? 
High-fantasy will always be my favorite but I think that a setting and campaign that the GM is passionate about usually ends up better than one suited to the players' wants.

>3. Preferences of Combat, Exploration, Role-playing, Moral Dilimas, Puzzle/Traps, Crime, Murder Hoboing, Meta-Gameing, Power Gaming, Politics, and War/Nations. Just list your favorite 3 or 4, and maybe give me some insight as to why. 
I'd definitely love to see creative challenges that depend on role-playing/acting, critical thinking, and tough mortal choices way more than inflated challenge ratings and dice throwing contests. I love building a strong character for combat as much as anyone else but having tough challenges outside of combat is where tabletop games can really shine, since there's no game engine to limit us.

>4. How active do you like NPCs to be? Do you like having them in the party or at least strong enough to survive following the party, or do you prefer them to stay on the side lines so the PCs can enjoy all glory? Maybe a mix? Why?
I know a lot of my answers so far have been "no preference / whatever you want" but I really do feel like playing in a world where things function the way the GM designed it to makes the experience live and breathe better. Most campaigns aren't super small in their settings, so a wide range of different NPC's would make the world more believable.

>5. Bigger or smaller groups?
Small groups give each player more time to take the spotlight and have their fun. If a lot of people are playing, then making multiple 3~4 player groups will run much better than one mega group. Letting these parties meet and interact will also be an interesting dynamic if it happens.

>6. Homebrew cool?
Talking from experience, there's a lot of work that needs to be done to make sure homebrewed content is fun and balanced. It's certainly a lot of fun when done right, but I've seen campaigns and playgroups fall apart because people either dont see eye-to-eye or the made up content is way too strong.
