RE4 is one of my fav games, I would not say it was scary, but it had a few moments.
I really am just glad Routine is bringing us back to combat being scary. I mean most games these days dying is just WHAT HAPPENS and then you reload a save, its hard to care about living or dying, its an inconvenience.
The FPS plus a more immersive way of handling the UI will help 'get into the character' I think, completely no HUD at all, all menus are used in the game in real time, you have to check your 'gun' etc, I like the way they are approaching it to make it feel very tense, but in an exciting way, not in an WHAT THE HELL GAME WHY DON'T I KNOW WHAT I'M DOING way.
