looking some Multiplayer online games

Rainbow six siege is pretty fun and 15$ right now

It depends on what someone likes but there is a number of good games to play.

Starbound, Minecraft always fun to build and explore.
Payday 2, Borderlands 1, 2, Pre, Left 4 Dead 2 good if you like fps games with a story.
Wurms, Bomberman, Mario Kart are great classics.

Divinity: Original Sin 1 & 2 *RPG* keep in mind this game can be hard.

You and your gf should play PUBG duos, itll be alot of fun trust me, amazing game.

Trust me, there are a lot of Multiplayer games, you just need to pick your genre. I personally recommend Warframe.
