Left 4 Dead is a great game that everyone should play, although the inclusion of only four scenarios is a major drawback. Valve will hopefully rectify this in the coming weeks and months. If you are a zombie fan, this is a game you must own now. If you aren't, you may want to wait to see what Valve does with the title down the line. One can only hope that Valve learned from their mistakes with Team Fortress 2 on the 360 and they give Left 4 Dead a chance to thrive because there is no other game on the system like this.
