An NPC companion system will be implemented to help keep the game solo friendly, but characters will be proportionally rewarded if they choose not to use this Tibia Gold system.
Players will be able to advance their characters to the maximum level without ever joining a group if so desire. Most content will be designed in a solo-friendly way, though often with mechanisms for scaling up in difficulty when more players are involved. This will give players the option to experience the game whichever way they prefer.
PvP: There will be two types of PvP available in Guild Wars 2; World PvP and Structured PvP. World PvP will allow you to play characters of any level.
All PvP-participants will have access to the same skills and gear, which ensures survival is indeed of the fittest (and most strategic), not the one that has spent the most time online. It is intended to be a more relaxed bridging point between PvE and structured PvP.
It will be on a larger scale than the original Guild Wars PvP with large battles which could take place over a long period with people coming and going.
Victory in World PvP will confer benefits to your world. This may include improved drop rates, better energy regeneration or other bonuses.
Party size in World PvP has no limit, and you can charge into a limitless battle.
