Most people will like it, though some won't, I loved it though.
THIS GAME IS GOOD FOR YOU IF:
You like exploration and experimenting - there is tons of dangerous island to explore, and there are infinite rooms you can find hidden money and items in. Experimenting - customizing weapons is great, plus tons more.
You want a game that lasts long - This game will last almost as long as an Elder Scrolls game or Fallout 3
You like a little challenge - this game can be a little tricky if either you have a big horde of zombies you have to fight off by yourself and with crappy weapons, or if you are stranded and need to get back somewhere safe.
You love co-op - then again, who doesn't??
You are an achievement hunter - The achievements for Dead Island are both challenging and fun to achieve.
You like gorgeously colorful visuals.
THIS GAME IS BAD FOR YOU IF:
You dislike zombie games
You like games with good, clearly presented stories
You find slower RPG's boring
You have a hard time digging deep into RPG's
You can't put up with mild repetitiveness.
You REALLY care THAT much about bad voiceovers
