I came away with a positive impression of Evo. The climate system was tense and strategic. It almost falls prey (pun intended) to Small World bash-the-leader syndrome, but has a couple of tricks to soften that. First, you can never attack someone who is down to only two dinosaurs. Second, the defender of an attack has a built-in advantage. Despite the less-fun theme, I would easily recommend this game to Small World fans.
