It's a desired departure from the fast-paced gameplay that happens to be in majority of games, meant to be more realistic. The ammunition is limited, really makes you think twice before using any of them, also makes you looking for another ways and methods to process ( Stealth mode / kills, decoy with bottles , bombs to take a group of enemies ).
The melee combat is very well made and animated, it is not about button mashing, its about what enemy and when you strike ( God I hate Clickers ), also about how well you are equipped, certain enemies require certain weapons ( shivs for Clickers for example ).
The whole feel of " surviving " is great, creating item, keeping your head down, getting back your arrows from dead enemies ... etc
EDIT: I love sixaxis usage in this game, not so meaningful, but really helps the theme of the game and the sense of caution

I'm playing it on hard mode by the way. Everything probably is less demanding in other modes, I really recomend the hard mode. Not really that hard when you know what you're doing.
