A must have for everyone!
A lot of great features have been added to it since the previous episodes. I like the ability to coninue from points without always having to save. I also like the ability to free-aim at the targets. Although I would have liked to see a bit more realism when you nail a zombie in the head with some lead, its a bit fake that some of them take 2 or 3 shots to the head while in the previous games one well placed shot could bring them down.
I also would have liked the camera to zoom out a bit further when you manuevering the character so you could see what obstacles are at Leon's feet.
Those minor issue's aside its a much better game than any of the previous ones. Its much more detailed and longer than the old ones (the previous RE games always left me wanting more at the end).
The merchant character is also a really nice touch to the game allowing you to purchase and trade weaponery and items.
The best advice I can give to a new player is to use choke points or the zombies will surround you and take you out fairly quickly.
That and be prepared to be drawn in to the game!
