I would like to have this option but with NPC's similar to the Adventuring Fellows we had in FF11. Each personality type would have their own story line. we would be able to level them up by taking them out to fight with us. and if a player wanted to romance them they would have that option appear depending on how the player interacts with the companion. i think this is an an area that has so much potential. there are a lot of players that don't want to marry another player in game for many reason. but this gives the rest of us that option.
