More believable world

Even though there have been numerous Resident Evil games that haven't used the series' trademark pre-rendered backgrounds, the game worlds have always felt rather lifeless. Whether it's just a hanging object that refused to budge when you walked into it or a general lack of destruction on all but specifically placed items, even games like Resi 5 felt somewhat dated. Small things, like how you can shoot holes through doors and collapsing huts in Resi 5, certainly helped, but despite looking far more impressive the environments often felt just as non-interactive as those in the older games.

Better Physics

Shoot an infected down in a recent Resident Evil game and it'll likely fly backwards and awkwardly land on its arse. Try shooting one while its moving down some stairs and you'll witness some truly dated looking physics, paling in comparison to what we've seen in games like GTA IV and Star Wars: The Force Unleashed. Resident Evil 5 looked amazing, but physics weren't a strong point. This would obviously tie in somewhat to the more believable world, with objects interacting with you and the enemies. Imagine shooting an infected cleaning through a window, down a staircase and into a group of other infected, knocking them down like bowling pins.
