[member="Ryan"] - A few things. Building for sandbox and Pvp. And, building for Character and building for Stats.
Private Sandbox: - For Pve, private threads, or just RPing with close friends. It doesn't matter. Be as strong and as god-like as you want. In a private thread or a personal storyline. You can be whatever you want to be. Blow Anakin Skywalker, Rey, or Kylo out of the water. Make the EU's Aboleth look like bathroom tissue. Whatever. Nobody cares. Anything goes as long as you and your writing buddies are having fun in your own little private thread.
PvP: - Second, however. Pvp. Here you got to have some give. In Pvp you can't go around playing God and smashing Padawans or Stormtroopers or Mandos like they're candy. Instead, you've to communicate with your partners about how to build a fun, balanced, and moderate theater. In Pvp, less is more.
Character Writing: - For character writing your thinking about people. Theater. Drama. Strengths of personalities. Lifestyles. Hardships and birthrights. Careers, life goals, hobbies, and passions. Everything that makes a real person, a real person. Build a person, give them dreams and goal, hardships, hatreds, and disadvantages. Soon. They will write themselves. Guided by the light you've given them.
Video Game Stats: - Building for stats means thinking about RP as a video game. Levels, XP, Hit Points, Attribute Modifers, and DnD cliche's. This is fine as long as you remember that writing fan fiction has none of these things. They are scaffolding and outlines for your character at best. At worst, you are just limiting yourself, your imagination, and the number of people who will care about your writing. So by all means. Think of your character as pure math if you must. But always remember that good theater never needed damage modifiers, meta builds, or legendary loot tables.
