The only reason people are shitting on Dead Island is because they got their hopes up for some epic story based solely on that one teaser spot that was made by a completely different company.
I watched HOURS of gameplay and I saw a few buggy spots, but people are complaining like assholes instead of noticing how great the graphics are for an "open world" type game, the lack of loading times, the driving mechanics are decent, the multiplayer is a ton of fun... etc.
I'm sure it was because of the trailer.
