I know that the duels in this site aren't very long. All are based around tells, luck and intuition. I'd like to see a multiple turn duel like RISK, or maybe a poker game. But something that is not over before it has begun. Maybe it could be like having multiple duels and a save file. Like RISK: P1 attacks from Home to Nutral with 3, P2 defends with 2. P1 has 3,4,6, P2 has 1,6. P1 loses 1 soldier, P2 loses 1 soldier.
Before and after each battle, a map could be displayed showing territories, routes between, and troop strength. Then the attacker could choose what to attack and where to attack from. To make things short, we could have only 3 territiories per player. I say per player, because this could be 3 PLAYER!
After the attacker has attacked and moved troops, the game is saved and the next player becomes the attacker. This can go on until all enemy troops have been eliminated.
To expand this idea, you could also have: 3 different kinds of troops with an advantages triangle, different types of terrain and a 100-point maximum bet. This may seem too much, but THIS HAS TO BE BETTER THAN GENERATION AFTER GENERATION OF RPS! if you don't like this idea, at least put in a poker game.
