Yeah I do the same thing too, when I play a different character I just start acting different XD Tiv makes me silly, Spooky makes me more edgy and bad tempered, Sae makes me....well Sae is sort of hard to put adjectives to :\ (we actually talk about this odd phenomenon a lot in guild chat when it's really late at night XD)
I should really play my other alts more to see what they do to me
*EDIT* also, I was thinking, if this RP thing gets going, perhaps we could have a set time for it? Not something concrete, just, like, "from 8pm PST to 12am PST (pst being my time zone, it can be any really XD) we'll be coming in and out of the RP tavern" or something....or even just saying "saturday is RP day!" works... of course people could RP whenever they wanted, but having a time where everyone is more likely to come on would be nice
it's not as fun RPing by yourself, after all.
