Recommend me games for my dad plz

He is recently divorced, extremely lonely, extremely boomery, and has a gambling problem, so preferably something with online play and no micro transactions. Does that even exist?

Since Covid he’s gone from married and occasionally doing a poker night with friends to divorced with his own apartment. He sits alone all day chatting with virtual poker folks and he is in desperate need of something to replace his addiction, preferably in a way that’s less isolating than text chats with strangers online.

Basically, I’ve effectively cut him out of my life, but him asking me to set up a new game on his computer is the closest he’s come to wanting to change in about a year. Any recommendations? Is Minecraft still free of micro transactions?
