Gamewise, I grew up on old school, tabletop D&D. That led me into all kinds of other tabletop RPGs, but after moving a bunch of times after college, I haven't had a stable gaming group for years. So at some point, I started playing computer games. I got into turn-based strategy games for a while (MOO2: Battle at Antares and Civ 3 were favorites), and then moved on to some single-player adventure games. BOTW was amazing. I played a few games straight through, back to back. Then, when the Little McGee mentioned taking the Switch to college, I ran out and bought myself a PS4.... only to discover that BOTW isn't made for the PS4. Drat. The Little McGee then bought me Skyrim for Christmas. For a 10+ year old game, holy cow! I played it several times back to back all the way through, and it's still a standby when I can't find anything else I want to play in my game library. Horizon Zero Dawn and Horizon Forbidden West are also very good.
Handy cheapskate trick: Check with your local libraries. Mine has PS4 games I can check out and play for a couple of weeks while I decide if they're worth buying.
