Hive / 2 players / Requires basically zero setup. Game is easy to pickup and a bit strategic
Star Realms / 2 players / Requires shuffling, separating some cards out and dealing out a few cards. Rules look daunting at first, but it’s pretty straight forward after a few games. There’s a mobile app if you want to try the digital version.
Fox in the Forest / 2 players / minimal setup
Play these with my wife and they’re all good for a relatively quick game. We’re not a big fan of largely random games and prefer something a bit more strategic.
