Hm. I try to optimize (context: try to influence) a broad spectrum of possible character choices.

1) I try to create characters that are easy to integrate and are eager and willing to engage the content.

2) I try to make use of recognizable archetypes, so the rest of the players can als envision/have immersion when I have my character take action.

3) I try to work with the gm concerning hooks and flaws to be integrated

4) I always try to build something that also enhances the fun and effectiveness of the whole party

5) Mechanically, I always try to have strengths and weakness of the "character" and "character build" match, also trying to stay within the overall floor and ceiling of the group power level.
