I recommend cs:go because it is relatable. Its a modern fps with two different teams, and you shoot at each other! £15 well spent! Enjoy!

I recommend ark because of its diversity. Its a multiplayer, or singleplayer, dinosaur survival game. Fun and good to play, buy on the sale and enjoy!

I would personally recommend tf2 because, although its old, its still fun and VERY diverse. Its a fps so shoot away but still, its f2p and fun! Enjoy!
