The guys at MMORPG.com have posted a
short interview with Global Agenda's executive producer Todd Harris. Here's a clip:
How is PvP beneficial to players? What rewards are available?
Global Agenda PvP does earn your character experience and credits, so players can choose to level entirely thru PvP or entirely thru PvE or a mixture of both. We offer many additional rewards via an achievement system and there are a set of optional achievement-based rewards for PvP contribution in addition to PvE contribution.
AvA Campaign activity yields player rewards and/or agency rewards but the specifics are really up to each agency around what they want to maximize.
Not much new here, but interesting.
