Having an AFGNCAAP player character doesn't work for games where the player character is supposed to be the main character and the game isn't a sandbox game, platformer, etc. There are at least 3 ways to have an AFGNCAAP:
1. Have an antagonist or another NPC drive the game's plot.
2. Have the player's allies and/or party members do the moving of the story direction with the player providing a managerial role, a "behind the scenes" authority or an "unsung hero".
3. Set it up where the character looks ambiguous, but is actually a character with NPCs a set home, etc.
