I made a list on Backloggd a while ago for this kind of thing! Some of these are just a little long for a single evening, but most of them would work for this. Some of my higher recommendations from here for a single-sitting would be D, Fairune, Ico, Kolibri, Mansion of Hidden Souls, Moon Crystal, Panic!, and Shinrei Jusatsushi Tarōmaru. In particular, Fairune and Mansion of Hidden Souls would be great when you and the buddies want to really sit down and think through things, while Panic! and Shinrei Jusatsushi Tarōmaru are great for nights where you just want to see a whole bunch of wild nonsense.
