Most of this has been said before but I'll chime in too.
I played Armageddon twice, and both times ended up leaving.
I've played on a lot of different text games, and before I started MUSHing the games I played were MUDs. Some RPE, some RPI, I liked trying new stuff.
I found Armageddon to be just about the least newbie friendly a game could possibly be. There was an approval process for characters that would often get sent back for edits (I got one because a person of whatever race or culture I picked would not have the eye color I listed, so I got to write it over.) So work is put into creating a new character, which is fine it is on lots of games. But. As a newbie you have to find a source of food, a safe place to sleep, etc etc or you won't last your first hours of play. This may seem like oooh gritty fantasy but it is really just tedious in practice. After one afternoon of 'you are starving to death' messages and no source of food that I could just buy or even gather, I was dunzo.
Second time I gave it a go was about 2 or 3 years later. This time I joined a clan fairly quickly so I had tons of food, and tons of supplies to use to practice my skills (I made a crafter) and some people who would look out for me. I was working on some crafting while rping with a guy in the clan and finished a shirt, it looked cool! I decided I wanted to put it on. And then here comes the thing that we've discussed on these very boards, the moment where in changing my shirt it wasn't handwaved but instead the dude present said something to my character about her nice tits.
I know some people who LOVE it and that's cool by me. I did not, the reasons above are two glaring examples but there are others, I could go on. The reason it is not my jam is not that I can't handle the 'gritty' atmosphere (their words not mine, I don't see a lot of grit just annoying details) Rather it is not my jam because there's so much focus on things that are wastes of time and less focus on things that are fun for players.
Caveat: Both of these experiences were late 90's early 2000's. A lot may have changed.
