I need an experts advice!

My one year with my boyfriend is coming up and he loves video games! I want to get him a game but I’m not sure what is popular right now....

He also has the switch so I could get him a switch game too. The problem is he always buys one for himself if he wants one.

What is popular or really fun games?? Hes not too big in the killing games with guns and stuff

I need a gamers help!!!!!!
