An interesting update of the classic table-eating game, the third edition is more focused, and more narrative driven than the previous version game. It comes with four scenarios, and 12 investigators (so there's plenty of replayability in combinations), and the scenario determines both the narrative (as is traditional, the game recommends starting with Azathoth, who bring wibbly-wobbly sanity sapping events), and the monsters which are like to appear (mostly cultists). The end of turn mechanism involves drawing event tokens from a bag, and only returning the tokens when the bag empties: this ensures that all the events will happen, both beneficial and terrible; it's just a question of in what order.
The narrative will make it easier with new players (as there are obvious things to do, rather than relying on experienced players to have a feel for efficient starting options), and considerably shorter playing time (3 hours or so). It'll be getting more table time than the bloated 2nd edition does (although 2nd edition will still come out for those special occasions).
The box includes a getting starting guide, so it's possible to start playing immediately after organising the components, without having to read the entire rule book (admittedly, we lost the first game, but it was playable. Replaying it added deliberation and understanding from our side, so we won the second time).
Obviously, FFG's production line will start churning out expansions by the truck load.
