Planeshift is different than most MMORPG's. Along with improving your character and gaining money (trias), you'll see from how others interact (as LigH stated), this is a "deeper" game. Place yourself in your characters shoes and "live" how your character would.
Use your imagination.
Ah, just a quick addition. If you happen to come by the Stonehead tavern feel free to say hi. I'd be happy to help you out.
