Isn't Hera & Zeus/Thunder & Lightning just a card version of Stratego?
Well, in the sense that there are secret cards with hidden strengths that then get compared, yes. But it's got special abilities and an interesting mechanism for action point allowance that makes it a better game than Stratego.
My biggest beef with the original game was constantly having to peek under my *own* cards due to forgetting what I had where. This game could really benefit from the Lord of the Rings: the Confrontation treatment.
