Here's my take on being friends with everyone in EVE.
Good friends are good, good enemies are great. Good friends in EVE will make you log on and chat, while good enemies in EVE will make you log on and undock.
I pick my RP enemies much, much more carefully than my RP friends, because they will have a greater impact on my game overall. In short, theyre often more important.
Do I like them OOC? Undoubtedly. Thats why I want to play this game against them. Its like poker, its more fun when playing against your friends.
EVE, at its best, should be about conflict and competition. Generally, the people who try to be friends with everyone in the game IC often find their way out of the game, for lack of anything to do. Theres a reason for that.
