How close are they? If I don't like Exceed should I avoid Battlecon? I don't think they're that close. Imho, Exceed is a lot closer to Yomi (second edition).
A fellow in my board game group who prefers strategical games commented that Yomi felt completely random to him, while he quite enjoyed BattleCON.
While I don't wholly agree with that assessment, there is some truth to it.
