I've created like 5 characters now, and with each one it's more fun.
Same goes to the weapons, you just play the way you wanna play and your character gets better at it.
Don't get me started about the mods, and the creation kit, i'm sure you all seen what people can do with it.
There are many kinds of atmosphere, so it can be funny, scary, sad, amazing, not just one kind of feeling that a game gives like most games do, every area in this game feels different, also depends on your actions, who you speak to, what you are, I can't give examples without spoiling so i'm not gonna give any examples, you'll just have to believe me and umm.. buy the game!
