I don't want to make a PW, but from time to time I get bored and wouldn't mind playing graal. Sadly, Graal bores me more so I don't play. I remember having tons of fun on Prov when they had the boats and RP, so I think someone should make a PW like that, or something like it.
It doesn't have to be all too complex. Just make sure you have boats, day/night system, and enforce RP.
Oh well, probably bad idea, but just something I always wanted.
