"Cheese" is an old gamer/mmo term for anything in the game that allows you to exploit to gain a distinctive edge against the environment or mobs (zombies/critters in this case). 7d2d is absolutely drowning in cheese, it is easily exploited. New players do not realize how much cheese is available to them even with A18, things they could do that are available right from the moment of entering in the game. As such the game is harder for them and an experienced player quickly outpaces them in gamestage.*examples*
1. I started a new server map a month ago due to moving away from experimental and switching to stable with my comrades. During the first few minutes of the game I had breezed through the tutorial mission and headed for the trader about 1KM away. Along the way I grabbed every nest for feathers/egs, every rock, grabbed a few hundred wood/grass all while running to the trader (still no cheese, just experience so we understand the difference). I get outside the trader and theres a bear there, and a mountain lion (all of this is true story btw). Rather than avoiding them like the plague I aggro them and sprint inside the trader before they cant reach me, using the terrain to stay just ahead of them (minor cheese, jumping on rocks, using pathing exploits). Once inside I close the doors because the trader depot is invincible to them (bigger cheese). I lead them to a small opening in the fence where they attack like crazy doing nothing to the depot. I quickly make a wooden spear from the materials I found and proceed to kill the bear, the cougar, I make a bow and aggro a nearby couple of lumberjacks and spear them down too for good measure and I am now suddenly somewhere close to level 5 (HELLO CHEESECAKE!). I have been in the game for less than 30 minutes, server is on standard difficulty. I THEN finish my "find a trader" quest with several more points to start with and start doing burial treasure missions.
2. I wont mention the nerdpolling exploits and other things you can do, they put the last cheese to shame and essentially make the game easy mode when doing fetch missions. I'm glad they are increasing rewards for clear missions to give those more incentive, at least those can be a challenge.
