Quacks is one of my favorites for a few reasons:

1. It's very easy to get to table, especially with friends who aren't super into board games
2. There's a lot of permutations of rulesets you can follow, so strategies don't get stale
3. It's a push your luck game, which I understand if people don't like, but it leads to fun interactions where you can peer pressure your friends into drawing more than they should. The luck aspect also means that it's easier for new players, for example I've been beaten by first timers just cause I drew poorly. Like I said, might not be everyone's thing but for new groups I think it's better if they stand a chance lol

Cosmic Encounter is a little harder for people to get in to, but once they do it's also got a lot of variety of strategies with the different aliens you can get, so it doesn't get stale

Another easy to table game is Betrayal, but we've played it enough to the point where we know most of the haunts and are kind of fatigued with it.

Most often, however, we end up playing Blood on the Clocktower. It's not quite a board game, more like Werewolf except it doesn't suck. I highly recommend it if you've ever been frustrated with Werewolf/Mafia, or if you've played (or watched) Gnosia. You can buy the game or DIY your own set as you can find the instructions online.

For my circle that's more board game enthusiasts, we like Wingspan, Nemesis, and Libertalia. Some older games that we don't really touch anymore are Terraforming Mars and Root. They're not bad but for our specific group we take forever to finish them and end up strategizing in ways that discourage player interaction.
