Trion is taking a page out of The Secret World's ARG book if a new dev post on the RIFT forums is any indication.
A company representative has taken to posting poetry, cryptic messages, and even a numeric user handle on the title's official boards. Thus far, RIFT fans believe that the user name 3 3228466 787 is code for three-faction PvP (or possibly three-faction RvR). Is this a herald for a third RIFT faction, factional changes, more races, or something to do with the mercenary system? We're not sure.
We are sure it's entirely coincidental that Trion is doing this on the same day that Funcom has lifted part of its press embargo for The Secret World, a three-faction MMO that has been marketed via similar ARGs since 2007. We'll update the post as more info becomes available.
