I played a lot of MUDs in the 90s as well, even used Tintin++ to "multi-play" as well. Those were the good old days! I might even have copies of my tintin triggers somewhere. Or maybe I was using it on a local freenet and they're all gone now... I don't know. Maybe I'll find it. Favorite MUDs that I can recall the names of were Mystic Adventure and VikingMUD. I believe I stopped playing Mystic Adventure when they stopped allowing powerlevelling, and I got kicked off of VikingMUD for using my high level "wizard" (which could contribute code and do other things) to level up my second character. lol...

Eventually local BBS's MUDs had a more interesting social setting for me than the internet ones, so I was playing MajorMUD when UO and EverQuest came out. And I was super interested in these new "graphical MUDs". In fact one of my friends from a local BBS got me into EverQuest in the first place. I remember he practically disappeared altogether when EverQuest came out, because at that point the only reason to "play" MajorMUD anymore was to watch a program play it for you in order to compare your internet points to the internet points racked up by other people who watch a program play it for them. Which was then no longer fun because the real point of having it played for you was to get higher level (so you wouldn't have to do *months* of work by hand in order to get a handful of levels) so you could go adventure at harder spots with your buddies. No adventuring buddies, no reason to play. On to EQ!

I also "multi-played" for years in Tele-Arena, Swords of Chaos, Insanity Complex, and a bunch of other MajorBBS/Worldgroup MUDs before MajorMUD. The multiboxing concept was roughly the same, but the execution was different. Back then you usually would have to send a message in the game to your second character with a secret code, and then your second character would read the secret code and initiate the appropriate action, which really was not far removed from botting. It's completely different now, our multiboxing tools are not designed to determine information about the state of the game and can't easily respond to that sort of trigger like we did with text games (and we don't want to because it's not allowed anyway).

Anyway, 100% yes.
