An engrossing and incredibly nostalgic examination of the role instant messaging clients play in forging and maintaining relationships - both when they work, and when they don't. Play the predecessor first, then come back for more. And play it like you're 16 again.
Stealth fans, ignore everything you've read here and buy this game - this one was made for you from the ground up. For everyone else, ask yourself what you liked about other more stealth-lite games you might have played. If it wasn't studying patrol routes for minutes at a time, give this a miss.
