From an entertainment point of view, you not finding the calipers was probably an enjoyable plot line for the viewers. Didn't they comment on it and laugh, and it was a thing they talked about?
I actually enjoy watching Kickz more than I like playing the game. A Large part of that is his reaction to frustrating situations, or continually getting annoyed with certain mechanics I know are broken but the devs don't seem to care to fix. The youtuber makes it interesting, the RNG makes it interesting. If you're always going to get whatever you need because you can perk it or build it or buy it then that whole element is gone. Which in turns takes away from the enjoyment of the viewer. The player, ya, I can see them/you, being frustrated but that's survival. You don't magically get the ability to do something just because you killed enough zombies and oh boiiiyee hot damn, now I can make calipers. That's not survival. But then, is 7dtd a survival game anymore? Once skills go in I argue it's moved past survival into something else, and clearly we're leaving the sandbox now too.
I hear you saying you are glad for it and don't like RNG but the simple fact is, it adds so much game play
What I would REALLY like now Fun Pimps, is an option to turn on/off RPG elements, or play Sandbox mode. So none of the rpg elements are around to bore the game. That way we can keep getting the graphical updates, ai changes (I'm sure it will improve) and other elements of the game that are good, but remove the RPG so we can still play a sandbox mode. And no Creative Mode isn't the same thing.
This way the fans that love the way the game was can play the way they want, and those that like the rpg/fallout role could play that one. It's not even having two games, it's just not forcing one segment of the game on everyone. Lots of games do this, allow for a sandbox mode.
