I saw this Lemmy post, but a huge list of games with no discussion isn't very interesting! Let's talk about why the games that influenced us had such a big impact - how they affected us as people.
For me, it was the PC game Creatures. It's a life simulation game featuring cute little beings called 'Norns' which you raise and teach.
You can almost think of it like a much cuter predecessor to The Sims, but which claimed to actually "simulate" their brains.
As a thirteen-year-old it was the first game that made me want to go online and seek out more info. What I discovered was a community of similar-interest nerds hanging out on IRC chat, and it felt like for the first time in my life I had "found my people" - others who weren't just friends, but whom I really resonated with.
I learned web development (PHP at the time!) so I could make a site for the game, which became the foundation for my job in software engineering.
And through that group I also discovered the Furry community, which was a wild ride in itself.
So yeah, Creatures. Without that game, I think I'd have become quite a different person.
I'd never heard of that game or the associated editor, but it seems fascinating.
I just had a poke around on the site, and it gives me some very good and happy vibes of how websites used to be, and the cosy communities that they hosted where all the regulars knew each other by name. Or by handle rather, since nobody ever uses their real name on the Internet, right? ;) Good times.
