I've only played two, two player games so far, but I can't see why I would ever try to collect two treasures from my opponent instead of battling it out to the death. Has anyone won a two player game, with an equal opponent, by collecting 2 treasures?
So far, my strategy has been to delay confrontation, perhaps by moving my treasures around a little, and collect items to equip. Once I feel strong enough, I confront the enemy, and go for the kill. If the enemy picks up a treasure, I follow him/her back, re-take it, and continue the attack.
I know the game's strategies can vary depending on the cards that you get and the changes in the boards, but has anyone won a two player game by collecting treasures?
