Okay, I'm going to keep this short, because I'm sure if I don't then noone will read the entire thing, expecially since I am only an on and off MUDder of about 3 years. Good things about armageddon? Well, there are plenty, but I'm gonna say the ones that -seem- to be bad at first glance.
First off, there's the level-less system, something that I wasn't too sure about when I first started playing. Since then I realised that it's one of the best things to ever happen to a MUD. It means that someone who's killed a few creatures in their life can't make someone explode with a slash of their sword. It just makes the game that much more realistic.
Second, the fact that there are no resurrections. I figured that I'd be submitting characters over and over again for weeks on end (well, I guess I did, but that's not the point) but really, after I got into the spirit of the game, I realised that it was amazing that you could acctually assassinate someone if you needed too. Not only that but it gives the player that same sense of survival and gets you into the game even more.
Third, no metal? What the hell will they use as weapons and armor? Well, it turns out that metal really doesn;t matter, because people adapt, make their blades from shells, bone or even wood. It just makes people want to keep playing to maybe get a glimpse of something mettalic, or, if you're really lucky, find some metal yourself.
And, lastly, basically the absense of magick in most of the world. This was the thing that made me most not want to try this MUD. I love magick, basically all my previous characters on other MUD's have been sorcerers of some kind. Really, all the absense of magick means is that any magicker could kick your ass! It requires alot of TLC to get to the place when you can play a magicker, but honestly, it doesn't really matter. The skill system on Armageddon is amazing and every thing about the game makes you lust for more. So much in fact that you'll find that you hate magic all the more just because your character doesn't like it. =)
