For many people the one consistent problem for zombie survival games using modern 3d graphics, well the ones with large open worlds and lots of stuff, is not being able to manage a lot of zombies onscreen at one time. Without large hordes, the game can still be good for sure, but it really can't achieve the kind of feel and gameplay that say a Romero fan would want. However, if we could have it all, I would have course prefer a game that has that as well as modern 3d graphics. Anyway, this game does look pretty cool, but yes this genre is getting very crowded. Not so much the zombies part, but the general open world post-apocalypse/collapse building/survival/crafting thing. I don't really mind though, because while there will be some poor ones the good ones could be the games I have been wanting for ages, and now even big business is taking notice with things like H1Z1.
