With the head start already underway (I saw people picking up their 
Tabula Rasa t-shirts with their pre-order today), the 
Tabula Rasa PvP ladder is populating with wins and losses from newly-formed clans like #1 ranked Critter Control Clan, no less than three Latin-named groups, and even the curiously-labeled Silence That Follows Us (STFU).  If you're itching for a science fiction MMO, this is where it's at right now.
