Interesting. Ive played a little Legion and it does not feel like Bolt Action to me. Mostly because of the movement, combat, and cover rules, but the activation system itself is actually quite different in play.
My only major negative at this time is excessive use of tokens and the non-intuitive cover system.
My son, who doesn't normally play miniature games, was able to pick it right up and really liked vadering my rebels. That's a major positive!
