Tintin++, TinyFugue, Savitar, Mudwalker and Atlantis are all designed specifically for MUD/MUSH/MUCK/MOO/etc. type games. These are different than door games.
MUD/MUSH type games send things like ANSI color, MCP extended sequences (which allow passing out-of-band data to plugins), MXP sequences (basically, HTML over telnet), etc. Door games not only send old-style IBM Extended ASCII (line-drawing characters and suchnot) where most Mac terminal applications are Unicode, but also in many cases will send ANSI cursor movement sequences (which many MUD/MUSH clients neither support, nor need to).
In short, the requirements for a MUD/MUSH/MUCK client to be useful are vastly different than those for a terminal client to be useful for playing BBS door games! I'm the author of the aforementioned Atlantis; I can honestly say I've never even considered using it for door games. It does what it's designed for, and door games ain't that.
I /do/ also play door games (gimme my TradeWars 2002, darnit!), but I've always just used MacWise. If you have the X11 package for OS X installed and need a freer alternative, luit should be sufficient to enable what you want in an ANSI-enabled X11 Terminal. It'll be slower than a straight Cocoa solution, and require a little more technical jiggery-pokery, but the price is definitely lower than MacWise. ;P
Luit's manual page can be found here, or 'man luit' if you have X11 installed on your Mac; it comes in X11 by default.
