Yes-ish. The revised edition uses unified phrasing, reworked cards and a modernized graphics design to deliver a more consistent and overall better (at least in our opinion) game flow and feel. Mixing old and new version parts therefore might create problems. Nonetheless, the overall mechanics of the game haven't changed, giving people with an advanced understanding on how the game works the possibility to "ignore" these problems; at least to a certain extent. However, we only recommend mixing old and revised edition for such "professionals".
