@Vebyast You might not have known this, but the author of the SAO light novels isn't actually an MMO player. In fact he designed Kirito based on how he thought of a cool MMO player that he wanted to be, without actually knowing the ins and outs of MMO's.
[LE GASP] MY LIFE IS A LIEEEEEEE!!!! *overdramatic sobbing*
Never seen SAO beyond the first couple episodes, so I have no idea who any of these are, save Asuna, who I think is the deutagonist.
She's the one who had interesting character traits, didn't know what was going on, figured out what was going on, became a major player in the game, and then fell in love with Kirito and lost all of her interesting traits.
Wait, I should probably specify a bit more.
EDIT: Aw dammit. Edit ate my rant.
Erm. She was the one he married, in game? I dunno.
EDIT II: To summarize the rant, shortly after she left Kirito's presence, she started to act like a character again, and nearly escaped the other VRMMO she got stuck in. She got done in by devs/mad scientists acting like idiots, got molested by one of said devs(who were in tentacle monster form, for
some reason), and then Kirito entered the same town/server shard/map/whathaveyou as her(which had expectable, if highly disappointing, results).
My point was that, with absence, Kirito-induced Bland Haremmite Syndrome will slowly go away! Just be aware that it's seemingly AOE with map-spanning range after it first takes hold.
