almost nobody here prefers fast gameplay, thats why so many people was disappointed with l4d, also, if they made a l4d clone, why would they buy this game instead of l4d?. We prefer a more tactical and anguishing approach
and l4d's big success is not the fast gameplay, there is not even such thing as big success other than the one made by the original hype and advertising it had
what I find funny is that you think its gonna make the gameplay slow, and others think its gonna make the gameplay fast.
I think it will just add stylish deaths, as it seems that ZED time is gonna be activated on counted ocasions for a few seconds only, is not that the game is gonna run entirely in ZED time, I don't think a brief moment of slow motion would bother anyone, when you are surrounded by zombies, you will find it most useful, and if you are not, I think you won't even notice anyway
