that and the story so far seems ripped right out of overlord

In general terms it looks very similar to overlord yea. Top game character getting sent into the game world a few hundred years later. But that's only on the surface. In overlord, the world isn't actually the game world. And while they're both their powerful 'evil' game character, in this one the guy doesn't try to play the role of evil overlord. That's only how people see 'her', and how 'she's' forced to talk rather than what she is trying to say. Also, no entire guild full of npc's that joined 'her' yet, and no being summoned in secret.
If anything, it feels like it has more in common with The New Gate. But then again, a most of these 'summoned to a game-like world' manga are very similar. :P
Just saw it's from the same author as SAO. Really hoping the story and characters are better than SAO. That being said, so far it looks interesting enough. Though not much has happened yet.
