I got this game for christmas, but why I left it this long until I played it I'll never know: the game is incredible, I'm not too far in just yet but wow.

Also loving some of the little throwbacks to the original game: Some of the original themes playing on the radio, someone whistling the main theme, mentions of the Luminous Path and Red Arrow, and I also picked up a eBook with mention of the UN considering a worldwide police (UNATCO no doubt) for the future.
Little things like that give this already amazing game its edge.
