Personally I like complex mechanics in my survival games, look no further than Conan Exiles. Problem with CE is you cant dig or destroy the map and well its not Zombies but the complex crafting system is realistic and very immersive and I hope 7D2D will get there or at least get close to that at some point. If not then no worries I am still going to be happy. I was talking with my friend the other day and the topic of "whats your favorite game of all time" came up. I explained to him that 7D2D is my all time favorite game because its complex in its own right and you have to constantly be playing. Whether its gathering materials by looting POI's to digging out an area of the map that you are making your base at. There is an infinite number of ways to play and you can literally do what ever you want in the game. There is no mundane story path you have to go through or anything. its truly open world and you can do whatever you want. He said League of Legends was his... a sad way to end that discussion in deed as LoL is the polar opposite of 7D2D.
I can't tell you all how many times my wife saw me running like a mad man through the house desperately trying to get back to my computer because i went AFK to get a drink or use the restroom only to hear on my wireless headset that my character was getting attacked by a Z. truly a helpless feeling. That my fellow survivors is how you know when 7D2D is your Favorite game of all time. Nothing is more evident than when your on the porcelain throne doing your business while listening hopelessly as your character is getting devoured.
if you want to kill this game just give it the Bernie Sanders treatment and give everyone everything free without having to work for it. I know that will never happen but the day i start a new game with a lvl 6 gun, lvl 6 tools, lvl 6 auger, Is the day i stop playing.
