First of all, calling RE series "horrific" is laughable. It isn't. Silent Hill was scary, Clock Tower was scary, Phantasmagoria was scary. The only "horrific" RE that I ever played was Gun Survivor, which is a FPS. Is a little ironic, isn't it?
Second, the daylight doesn't change anything. I'm not a 5 years old kid that is afraid of the dark, it is not the "night" that makes a game scary. Left 4 Dead 2 has a daylight campaign and it is very good, for example.
Third, the game is not that easy. Of course, you can play the same stage a thousand times, farm up ammo and gold and go to the last level, but it is up to you to play that way. You're free to put ammo/weapons on the chest between the chapters and make it harder, by yourself. Capcom does
not force you to use everything the game gives you.
