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.
