No, not that sort of Pawn Sharing. In the first of Capcom's four-part Dragon's Dogma progression videos, the developer discusses the details and benefits of sharing the many companions, called Pawns in-game, with your friends online.
Pawns can be recruited throughout the game, and sharing them online with friends will yield a number of rewards including, but not limited to, resources and wealth. Doing so will also earn you Rift Crystals that will enable you to recruit even stronger Pawns into your dragon hunting ranks.
Dragon's Dogma looks like it's shaping up to be quite the experience. It's out May 22 in North America and May 25 in Europe for PS3 and Xbox 360.
