Because that’s the best way to organize one’s ideas, right?

• Enemies may be in one of the following states:
• { wander, pursuit, flee, help(?), avenge(?) }
• Enemies and NPCs have levels (which linearly grows its power)
• Enemies and NPCs may pose as a threat to the other, if its level is higher and it’s nearby
• If the player kills a non-threatening enemy, its insanity grows
• It also grows if the player is nearby a NPC when it kills a non-threatening
  enemy
• The player recovers some of his sanity whenever it saves a NPC/Enemy
• At the end, the player will face the dark lord
• If the player battles it and defeat it, its insanity will increase quickly
• If the player goes insane, he becomes the new dark lord
• The player may not face the dark lord, but he will need a relic to convince the dark lord there is a third way
• This relic is only obtainable if *secret* (c’mon, I can’t spoil all the fun, right?)

Also, this will be the player:

I do wonder why I drew a cool guy with a jacket if I want him to defeat enemies with a sword… Oh well….

Now, time to get some sleep…
