It is not fair to compare an underwhelmed, mediocre game like b4b to the 12-year-old legendary game like L4D. ..unless they try to promote it as a spiritual successor of that game. You can’t just try to ride the fame of the game you barely had contributed anything to and get away with it. It’s false advertising and honestly, unethical.
While L4D has a very simple gameplay mechanic, there are so much stuffs that were brilliantly done behind the scene to keep the game engaging, fun and never get old. The AI director, the sound system and the storytelling from the world buildings. The well-balanced infected that can always be counter play by survivor and vise virsa. The fact that youtube has so many videos about the L4D characters dialogues and has so many views in each of these make it obvious how much passion they put into the game underneath the facade of a simple gameplay mechanic.
If people who claim to have played both and yet rate this one more than a star doesn’t understand these subtle brilliance, it is understandable. You have to have taste to detect something awful after all. … but for the turtle dev team who claimed to have participated in the L4D creation to F up all these detail that make the game so fun, it is either they are being lazy or incompetent or maybe both. Have fun playing this game, guys. Never mind having the game last as long as at least a decade like L4D, this game is goin to be just like Evolve all over again.
