If you play the "heavyweight" games listed in other comments, there's generally also a need for "filler" board games that are much shorter and useful when someone has yet to arrive or it's getting too late for another full longer game.

King of Tokyo (https://boardgamegeek.com/boardgame/70323/king-tokyo) and Tiny Epic Galaxies (https://boardgamegeek.com/boardgame/163967/tiny-epic-galaxie...) come to mind.

Also, Guards of Atlantis (https://boardgamegeek.com/boardgame/172965/guards-atlantis-t...) was interesting as a team-vs-team game conceptually similar to computer games like DotA or League of Legends.
