I'm not really surprised Sega decided that way, but i still feel that they are missing an opportunity here.
Obsidian created something unique here and with all the experience and feedback i'm sure they'd know where to crank up the scores in APII.
But as long as Obsidian can continue to create new IP's or at least do the games they want to do, it's fine by me. I liked the spy-theme and the modern setting, so anything in that area would be most welcomed But hey, i'm not picky. They just need to put in their sublime characters, dialogs and story all wrapped up in some grown up setting and i'm going to buy it!
