I’m a casual Half Life enjoyer. Spent some time on the subreddit and man is it off the wall.
Tunic has an interesting fandom. That writing system has inspired a lot of cool stuff. The subreddit is censored six ways from Sunday because of how spoiler-sensitive the game is, but I have to wonder what random passers-by must think.
The Undertale fandom has permanently put me off trying the game. It’s not really my kind of game anyway, but I enjoy the soundtrack.
Minecraft has to have had the biggest demographic shift in its player base I’ve ever seen. I bought the game when it was in beta. Most fans were adults who were able to give a random Swede 20 bucks via PayPal. After the game’s release, and especially after the console ports and eventual MS buyout, the average age got younger and younger. I miss the old Minecraft forums.
If you want something similar to old Minecraft, there’s Vintage Story which is basically hardcore-hardcore Minecraft. From what I’ve seen and can tell, the age demographic for that group is about early-20s+ as it has much deeper mechanics than Minecraft does (like accurate temperature and insulation, block gravity and cave-ins, actually physically shaping items into other useful items via forging or knapping, etc.).
I’ve only played for a bit, but it’s awesome. There’s a ton of mods for it already too.
Edit: there’s also a chisel mechanic in the game so you can shape individual blocks however you want, mix different materials together to create cool patterns and looks, and the edited blocks act like they should; like water and fish will go under if you make a bridge, you can make funky stairs or “slopes” too.
