This is a fantastic game that telltale has given us. The only reason I gave it a 9 was because of the controls. This is definitely not your typical 'see zombie, shoot zombie' game (although you WILL be doing that at some points).
The best thing about this game is the story. You are only playing this game for a good 5 hours but it feels so much longer and you easily get invested in the characters and their stories. I like that you have to make snap decisions that affect you and everyone else (which probably has the biggest impact at the end of episode 4) because let's be honest, if there was a zombie apocalypse do you really think it will be all fun and games?
So if all you want to do is mindlessly shoot every zombie you see, don't get this and don't rate it so low because you feel every zombie game should be an overplayed shoot 'em up game.
