Mysterium - something easy to learn and can be played by up to 7 people. One of the players is trying to tell others (psychics) who their killer is using very nice looking but rather ambiguous cards.

Maximum apocalypse - up to 6 characters doing different missions in different types of the apocalypse (zombies, nuclear war, aliens, robots). Map is randomly generated so even though there is limited number of scenarios they are replayable.

Sherlock Holmes consulting detective (multiple boxes) or Bureau of investigation - investigation in Arkham & elsewhere. These are text based puzzles (e.g. solve a murder case).

Spirit island - it's basically anti Settlers of Catan :) Still learning to play it but so far it seems like an amazing game with many scenarios...
