Summary of Game theory simulations.

Strategy which works: tit-for-tat.

Strategy starts off being nice.

Then replicates the actions of the opponent. If opponent is adverse, then self is adverse. If opponent changes to nice, then change back to nice. 

This strategy carries niceness, realistic pragmatism, and forgiveness. Resulting in long term predictability of the person and a brand building.

Caution. Short term games might be lost. Long term games are mostly won.

Modified strategy were the self tests niceness after a period of adversity results in even better long term results.
