Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

There are worlds in nwn1 where you need water to survive in the desert.

Something similar could be established for surfacers as well in the UpD and UD. Would make it a bit more difficult for those oafs to trample around.

- Underdark players on the surface, and surface players within the tunnels of the Underdark, who have been identified are considered to have consented to PvP and may be killed on sight. The exceptions are for the city of Sshamath and the Upperdark, where all involved are still required to follow normal PvP rules.

• Characters outfitted in a way that completely hides their identifying features require the aggressor to apply normal PvP rules, regardless of which side the disguised character is from. The disguise must be complete and hoods by themselves do not count. Patterns of speech, accents, body language, and other distinctive qualities are discerned only through roleplay over time, and details such as "a funny-sounding name" or the size of the character alone do not count for the purposes of identification.

Yea, some people definitely start pvp out of ooc "guesses".
