At Role Playing Online WWW.RPOL.NET
a FS game set 5 cycles after PK Wars is now forming. All original characters for the players, no TV characters at start.
RPOL is a well established online venue. It consists of text messages sent between the players either privately or publicly. Game play can be slow as players await responses to their posts. That is the only major drawback, though if you lead a hectic life it's an advantage. I recommend the experience for veteran RPG'ers. An imagination and good English writing skills are mandatory.
The game is in the Sci-Fi section:
Farscape-What the Frell is going on here?
I recommemd looking up the Western Game:
The Quick and the Dead
By reading posts there it will give you a very good idea of how RPOL works at its best.
