Its not fallout 3 with online possibility. Your not playing chosen one in it. Your just part of that world. Your quest is not to find geck or the water chip. And yes players get to walk around allot, online engine doesn't work like fallout engine where you switch maps. Its is one extremely huge map with towns scattered around on it. Players can even build their own towns. Most economy is based on players trading with each other. And distance between 2 town can take up to 45 minutes of walking and avoiding hard npcs and other players that want to kill you. And all npc enemies spawn. Means if you kill a deathclaw that you find in the wasteland after for example 60 minutes it will be created again on a different random location. That way its random encounter. And there are crafting skills like making ammo and guns and making armors and drugs. And there are skills like farming and mining to produce food and herbs and chemicals and metals and explosives wich players can trade with each other. They can even set up npc near their house to sell stuff even when they are not online. They just set the price its going to be sold for. And luck is easiest thing. The bigger luck you have the bigger chance there is that npc monsters drops rare weapons/house decorations/bigger amounts of money and so on. And all special system parts can be scripted to work exactly like in fallout. If interplay makes it similar to this i would play it. But if they make a ever quest clone in PA world than its going to be really lame.
