What are in your opinion 3 steps to fun roleplay? Or more fun if you prefer.
1. Never limit yourself to what is logical and reasonable: people in your actual life don't do that so why should you?
2. Be quick: try and think ahead and be as flexible as possible, because you never know when the guy next to you is going to drop the building down on himself to take out the dragon.
3. Don't be afraid to be the hero of your own story: It's easy to forget that the game is about being great; embrace that and push it to the limits.
