Yet Another RPG Open To The World Of Same Sex Marriage

Deriving information from Bethesda marketing exec Peter Hines, Bethesda has seemingly included the option to befriend and marry non-player characters of either gender, forming lasting benefits for the player to earn over the game. Companion NPC's might ask a favor of you (yay, extra quests) and in return may grant a favor, such as aiding you in a dungeon raid or battle.

Considering the recent inclusion of marriage elements in titles from Lionhead and Bioware, this doesn't seem all that surprising.
