Big lover of Munckin here, assuming all the add-ons are there, otherwise you start getting repeat cards too quickly with 4-man games. Takes forever to teach everyone the rules though, especially for the ones that could go either-way if it's not either described in the rule-set, the website, or the 'owner of the cards has last say'.
Catan.....I love the gameplay, but fuck setting the board up, takes forever when you have the expansions. Much better suited for a digital format, or on a
$15k table.
Will throw in the FLUX card game for good measure. Fast and fun with a group of friends.
Apples to Apples used to be fun, but once you played enough matches to know what all the 'instant win' cards are, it kinda loses its charm.
I also enjoy Puerto Rico. Game takes a few rounds to learn the ins & outs though, not exactly pickup&play. It's all about indirectly cockblocking your opposition with regards to obtaining worthwhile mats, and controlling the boats for sale of your goods.
