Running into a lot of walls myself. I have several 'not very nice' or at least slightly odd characters that I have been trying to play and I've had mostly really bad experiences when trying of late, to the point that I've withdrawn a lot from RP. To date, I've been insulted for my attempts, had people accuse me (the player) of being mean - yet I never target people I haven't witnessed as capable of RPing, been outright ignored, had people use OOC information against my 'bad guys' and in general have been left with the feeling that all people want is tavern RP or to RP about what craft they are learning.
I've nothing against those kinds of RP - if they are opening doors to deeper and more interesting developments, but by themselves they often bore me, probably because most characters I run into are flat and underdeveloped, have no quirks at all and do nothing interesting.
Sadly, I'm also guessing my timezone has simply become incompatible with RP on PS, because I know there are still some RPers around (and not to belittle anyone here, because I know there are RPers in my time zone, but I specifically mean the sort who RP deeper and more complex plots), but I'm just not running into them.
I'm no longer sure what to do about it. If anyone ever wants to prod me into RP, by all means do.
