RE6 was an unmitigated mess, featuring 4 campaigns with four lead characters, each with their own sidekick/partner and 4 very different styles of play. Leon was all about fast zombies, Chris was mowing down waves of enemies as if Gears Of War had never been made, Jake was all about hand to hand combat and Ada happened to feature the closest thing to a classic RE game in years, despite the fact that you had to unlock her campaign by beating the other 3 first. With each clocking in at about 6 to 8 hours of gameplay you had to wade through AT LEAST 18 hours of mediocre game to get anything respectable. It never used to be like that, the first game had you confined to a mansion and it's grounds while the seminal RE2 kept you cooped up in the Raccoon City police station, with your only escape being through the suspicious labs held underneath. Either way, claustrophobia and paranoia would set in as you did laps of the areas, solving puzzles and never really knowing if the areas would stay clear or not (spoiler: they rarely did). Having sprawling worlds like 5 and 6 had don't engender fear, you just blast your way through each linear area and move on, with scarcely a thought about where you are or what you're doing.
