Developer: People like this game? Let's make it so when a survivor has a melee weapon, they run into a gigantic horde of zombies to try and kill them. I'm sure everyone would enjoy using up medical supplies, using fuel, or wait a half an hour for them to heal. Hey Bob, you come up with good ideas. You got any?
Bob: Yeah. Copper wire and plastic are easy to get right? Let's put them inside of the store so people can spend valuable fuel on items that they can get super easily! The players would LOVE that! What about you John?
John: Let's put really crappy items in the shop that people obviously wont buy for MORE valuable fuel!
Andy: Let's make it so we can upgrade the car for shorter return time and put good items in the shop for reasonable fuel prices!
John: ...
Bob: ...

Developers: Oh, people like this game so far? Let's make it so if they have a melee weapon, they run into a giant horde and get incapacitated. They would LOVE to wait ten minutes for them to heal or spent fuel to help them get better.
Other Guy: Another great idea. Do you know how you can easily get plastic and copper wire from recycling? Lets all put them in the shop to spent shitloads of fuel on something that you can get super easily. They would absolutely LOVE that!
Other guy 2: I dunno. Don't you think that it might piss off players?
Other guy+Developers: *Pulls out guns and repeatedly shoots Other Guy 2*
Survivor: This compound looks in pretty good shape... WAIT A MINUTE! You have 6.5 days worth of food and not 7 days! YOU CAN FORGET HAVING ME AS YOUR ENGINEER!
