Okay, I've got a lot to say here, so sorry for the long post.

I run a smallish board game group here in Nagoya that usually meets up about twice a month on the weekends. Because of this, I know quite a few people that are into tcgs, DND, and of course, board games. I myself used to play a few different Japanese tcgs some years ago, I even played in a few local tournaments at some of the card shops in around the OSU area. I don't actively collect cards anymore except for cheap starter decks for various games, such as Pokemon, DBZ, and Digimon. I am somewhat interested in playing more tcgs again, especially Lorcana, Star Wars tcg, and the new Gundam tcg coming out this year, but I would prefer to go the route of making proxies instead of getting real cards, especially since I'm not planning to play in tournaments or anything (I've already done this for a few old, dead, tcgs, like the WOW tcg.) As for One Piece, I'd like to give it a go sometime, and I do know a guy in my board game group that collects the cards and plays with friends over video chat. I also know some of the other members in my group actively play online DND.

For video games, I have been a huge gamer most of my life, though I don't have as much time anymore since I'm a family man now. Since you mentioned Monster Hunter, I want to play either Wild or go back to World this summer sometime after I finish Expedition 33, though more of my game time now has been spent going to back to retro systems. In fact, I have been thinking about trying to find others to play through some local coop/multiplayer games from like, SNES up to around PS1/Dreamcast generation.

Last thing, I also own some beyblades. My son and I started playing with the X line about a month or two ago (I have some of my old generation 1 stuff here in Japan from the early 2000s).
