This is great!
I can actually remeber those RPs, they sometimes were a complete mess, but were always fun no matter what.
Btw for later RPs we even created a separate module to allow wearing different clothes. cRPG is perfect for this!
About broken english - it is never a problem, everyone can get a role: you can be a foreign trader or even some assasin who isn't good at local language. In one RP I've been an enemy scout group member and we were mostly speaking between each other.
Also, voice RP is great, for example one time we could spy an official meeting, it was rather hard to hear but that is just an addition to fun.
Another part of greatness in these RPs is that even though roles are predefined, only organiser knows all characters: you won't know if there is an enemy scout group, or how many guards are in a village.
Yeah, there are a lot of things laying on organisers, but even if plot isn't very great, people rule that event and it is still interesting.
