wow i just started reading some of the reviews ... most of them bad. I didn't play SM2 but I played most of 1 and found it fun. I also find it hard to improve on such a concept. Make it bigger, better, faster... okay so they did that. Most of the reviews are focusing on the companies that ported it to various consoles, but Activision was at the heart of the game. It's flow is and similar enough to games like Prince of Persia and TMNT, plus many of the controls and interactivity found in M:UA. So it's a nice blend of action and movement. You can spend hours doing anything but the storyline helping people, gaining reputation, taking photos, taking back territory for the police.
It really sucks this game is getting trashed. Like THX said, and from what I hear, it's selling fast. In the end, this one is about fun.
