In addition to D&D I own about a hundred or so other games; a mix of RPGs, miniature wargames, and some board games.
At present I'm playing in a Pendragon campaign and an intermittent game of Vampire: The Masquerade, in addition to the D&D games I'm in and the one I'm running.
I used to be a huge Warhammer and 40k tournament player, and have extensive armies for those. I played a great deal of 3rd through 6th editions of 40k, 6th and 7th of WHFB, and periodically still get in a 40k game in the newer editions, or Kings of War for my fantasy models. I have a decent-sized Cryx force painted for Warmachine as well, but haven't played that regularly since 1st edition. And armies for Stark and Lannister in the Song of Ice & Fire miniatures wargame from a few years ago. I was playing a lot of that for a while, though I haven't updated since the last revision.
My local gaming buddy who I most commonly play wargames with just jumped back into a Blood Bowl league at one of our FLGS', so I've just splurged on the current rulebook, a new pitch, and set of team cards for my main team from back in day (called Elven Union presently), and will presumably be getting in a few games of that soon.
I don't play any board games super-regularly, but there's a good community for them in my city, with a board game cafe/bar/restaurant right downtown on our main street, and I'm friends with a couple of groups of regular players. So every once in a while if schedule permits I can jump in there. Some of my other friends occasionally have (or had, prior to the pandemic, though hopefully we'll restart ere long) boardgaming days. Play some Lords of Waterdeep, Carcassonne, original DungeonQuest or Talisman from the 80s, Exploding Kittens, How Do You Meme?, etc.
I played Magic: The Gathering and a little Jyhad (now Vampire: The Eternal Struggle) back in the 90s, and got back into Magic in 2013, and occasionally play that. For a few years I was doing a lot of draft and sealed at local stores and tournaments, and keeping up with Standard for a bit (and dipped my toes into Modern), but I haven't really been buying or playing Magic in the last couple of years. I still keep up with it a bit watching streamers on Twitch in place of regular TV if I want to have something on at home.
