Watched the first episode: really liked it
I love how it mentions 200,000 people are trapped worldwide too and how, this time, you've got veterans (level 90 people) in the game....
I can't help but think, though, that this is kind of like taking Lelouch and putting him in an MMORPG in terms of story. I hope them saying Shiroe is a legendary guild's strategist will mean we'll see some cool strategizing from his part
