I've been reading some reviews for this game and I've come to the following conclusion:
Next Gen is the things, developers have been doing for years but, with better graphics. And everyone's supposed to shell out 5000$ for that?
Of course, game reviewers all over the world are falling for it hook, line, and sinker. The review scores this game has been getting are ridiculous.
