I always recommend roleplaying games like DnD or pathfinder as a hobby since it has a built in social and private element to it. You can join a group at most local game stores or by looking for organized play. Both Pathfinder and DnD have organized learning sessions where you can learn to play. Both allow you to start for free.

The good part is there is a regular scheduled social element usually weekly and between time you can do things yourself. That includes reading rules, making minis, practicing voices, writing modules, reading old source book, watching live streams, making maps etc. You don't have to do all of those but you can really go in depth or as shallow as you want. All of the things you do my yourself will enhance the enjoyment of the group which is a great as well.
