Are there any board or card games known to have been designed to feature OODA loops?
The phase layout for Munchkin practically is the OODA loop:


Observe:
Phase 0 - Check and adjust your possessions
Orient:
Phase 1 - Draw a card face-up from the Door Deck  


If it's a Monster: fight it and go to Phase 3;  
It it's a Curse: apply it;  
It if's any other card: put it in your hand or play it;  

Decide:
Phase 2 - Choose either "Look for Trouble" or "Loot the Room"
Act:
A. Phase 2  


If you choose "Look for Trouble" then play a monster from your hand and fight it.    
If you choose "Loot the Room" then draw a second card face-down from the Door Deck and place in your hand.  


B. Phase 3


Charity: Reduce hand to at most five cards



One could probably make a similar case for all D&amp;D-type games, but Munchkin is always the most fun. Part of the satire that makes Munchkin work is that everything is explicit in the rules.
