Telnet games? f*ck that, those are WAY geeky. Who the hell gets on a MUD these days when we have EQ and WoW, not to mention Second Life!?
Well I don't get on either of those nor MUDs, but that's besides the point. Ever since Meridian 59, the first commercial PC graphics MUD (AberMUD was first but for the less popular Amiga), text-based MUDs have been dead in the water.
So if this guy wants to try and sell Telnet games, good f*cking luck. Try the Linux community, I heard they still get their rocks off to text...
