RE6 is a gem, but you're meant to play it like a stylish character action game - rolling and diving and sliding and ducking and jump-kicking and shoulder-checking and perfect-parrying. Many people play it like a cover shooter and don't understand it. Also, you got a stamina bar and the ability to mix/dispense herb pills on a piecemeal basis, which is brilliantly versatile but confuses people at first. The four campaigns are worth it for the story but have a sense of too many cooks in the kitchen, throwing a bazillion ideas and setpieces at you. Mercenaries is where the game shines brightest. RE6 is one of my faves, but it can be an acquired taste.
