Question About Resident Evil

[Heyyoudvd]

First of all, let me just say that I'm new to the RE series and am interested in the new Resident Evil.

Anyways, does anyone know approximately how long this game is?

I've heard that it's a great game, but I've got no idea how long it is. It doesn't have any multiplayer, so If it's only about a 12 hour game, I'm just gonna rent it, rather than shell out full price, as it wouldn't be worth it.

Can someone please tell me approximately how long it is, and whether it's worth the purchase, or just as a rental?
