Any game suggestions i can play with my gf online?

I recently bought my gf a PS4 as she's wanted one for her streaming and she wanted to start playing games with me, but she's not really into games like GTA or COD so that's out of question. What are some games we can play online together that you think would be good to play besides games like the ones earlier or similar? Also co-op would mostly be best to suggest but any is great as well.
