Wow, Edward Nygma knows how to make a cool board! Stay away from 6-player games, as the cards will heavily favor later players, with the 6th player getting the biggest card bonus each time. Also, when playing, keep an eye on who has the central piece in every square, you are able to "see" the owners of each central piece, and in many cases (but not always!) be able to deduce that that player controls the whole square. That plays into how you want to develop your attack.

Not a straightforward board. Game mechanics are the same, but bonus structure is different from continents or hordes. Best played with little or medium fog, else the game is too open.

Beautiful board, fun and fairly simple bonus style and dynamics. Large bonus game where a solid start is critical. Tough to know when to break someone else's bonus and when to simply work on your own. Multiplication of bonuses makes for interesting play, and towers are nice too.
