all games are not created equal

Zombies zombies zombies.  Zombies are pretty popular these days.  Dead Rising may have been somewhere in the beginning of the zombie craze and L4D possibly near the end of it?

Anyway, Dead Rising is a cool game.  It's very much like the Evil Dead series of movies, where instead of keeping it totally serious the entire time, it can get pretty silly.  You may end up running around in kids clothing cutting up zombies with some hedge clippers.  You may even get a hold of a lawnmower or a chainsaw and really end up tearing up some zombies, and it's fun.  Only for a little while though, because the repetition can get pretty boring.  Also, searching for the right weapons can be pretty difficult, especially since there are zombies all over the place just waiting to eat you.

L4D is an even cooler game.  It captures the feel of a more serious zombie movie and does a lot of things right.  The zombie hordes can be pretty intense to fight off and the tank zombies can really stress you out, and it's awesome.

Both games aim to make a certain type of zombie flick into a game, and both do it pretty well.  L4D ends up being better because the type of movie it pulls from ends up creating more exciting gameplay.
