That guy who mainly did those space RP's, I remember playing his jail escape that he wouldn't host too often.
I also remember this really old prison escape that had a main square room with a bunch of doorways leading to different things, like the yards, cells, armoury, death row and such.
And finally, a load of RP servers from back in the day - I was pretty much a slut for them and I don't know why, I still do fancy a bit of roleplay here and there but not much can really scratch that itch these days.
