Reply #6: I have never played L4D, but I want to.

Dead Island is a lot like Boarderlands, except the graphics are realistic, you're mostly fighting zombies, and the maps are dense.

Dead Island is a large open world with tons of looting and missions.

The version released on Steam is apparently messed up. Here is an official message about it from their website: http://deadisland.deepsilver.com/blog.php?page=1

You may want to wait before getting the PC version, but the other versions should be fine.

I have played over 10 hours I have yet to notice any glitches, but I have read about people loosing some of their save data on PS3. I always quit in the game's options menu before I turn off my PS3, so that probably helps.
