The Last Survivors of Meridian 59 (2014)

I've been heavily involved in this project in the past. It's still going strong!
openmeridian.org and meridiannext.com are the most active open source servers.
The only thing more amazing than the game living this long, and it IS a great game, is that our bad actors in the community have been so dedicated.
The game's source code was released in 2011 and is available on github for old fans and new to create new worlds and game experiences. https://github.com/Meridian59/Meridian59
The population is not what it once was (it tends to come and go with the seasons, one player makes a huge impact in its world) - but it's worth checking out, historically.
There are now a couple, fan-run open source servers that have been doing a TON of work on the game, some offering more PvE, some more PvP based. Old fans may enjoy checking out some of the changes on these servers...or they may enjoy seeing something a little closer to home. Either way, the game is still alive, thanks to the fans. Users are still getting involved in their old relationships or making news ones, with some incredible stories due to the game being out for a virtual lifetime.
Being on Steam would be a great way to introduce it to new fans and it already has a 'workshop' with new servers and other mods via its open source community. I know many would appreciate it being on there - the more, the merrier. I think after 20 years, the impact such a boon could have is more positive.
['Netiquette' was definitely a part of the game's set of skills, with players policing their own servers and taking social justice into their own hands when members of the community were 'unruly'. In the years since, the social landscape of the game changed along with our internet culture, for better or worse.]

I used to be a GM on it, more than 15 years ago (!) -- it was one of the rare game on Mac as well, at the time when Mac weren't trendy at all..
Have these people never heard of a MUD?
In retrospect, there were a lot of things that Meridian wanted to claim we were first at, but there were people who beat us on almost everything: graphics in a MUD, 3D controls to a virtual world, etc. The one exception MAY be that we were the first MMO/MUD to have a box product and a subscription fee (most online games before us used daily or hourly charges, but we came out right around when AOL changed the billing model, and everyone else rearranged their billing models to match).
