1. NFU - I haven't truly written a NFU yet, however, as a D&D player I always struggled with non-magically inclined classes/characters and I've noticed that mindset also travels to Chaos. I love my warlocks, wizards, and clerics, etc...be they fantasy or Star Wars lol
2. Jedi/Lightsiders/Generally good people: I can write characters that have a streak of good morals/morality - however, I find it to be a lot more natural for me to write as a dark aligned/troubled/evil character. I want to write a Jedi and I might try my hand at it at some point but I already have a feeling that I will naturally gravitate towards the dark side with them lol.
3. Fleeting/spaceship fighting. Never done it, don't understand how the hell others do it. Not for me.
4. PVP. I can do it, I've written it. It's not my favorite thing in the world. Mostly because I am a very visual person in my mind and it is very hard for me to picture how my character will react to another PC's actions and if they do something that doesn't make sense in my mind, then I really struggle to figure out my own response.
