I hope they'll balance it out by making mineral water a bit more common perhaps.
Idk, the changes don't seem to be particularly well designed. Sacrificing depth to artificially make the game harder, while simultaneously making looting more annoying, removing items from loot tables to make those even more shallow, and so on?
How about making glass jars not stack, just like metal cans? How about making them require a mold to craft or something? I mean if they really wanna force players to have dysentery more and to be on lower HP all the time, surely there must be less annoying ways to do it?
"Never been done before" is a strong statement when many role playing games exist, including more survival oriented ones. It is absolutely possible to do a deep faction system where you can gain favor with different factions through different interactions with them, and have the NPCs act towards you accordingly.
If this is the plan for 7dtd, as it was stated a long time ago to be (with NPCs having schedules and the player being able to get either on their good side or their bad side), then I don't entirely understand why they'd first only put "zombies with guns" into the game as opposed to dedicating an update to do it properly right away. Like yeah, maybe it'll take a year. So what? This is 7dtd. After it didn't go Gold 5 years ago, it really stopped mattering when it actually ends up going Gold.
The trickier question is whether or not the engine supports implementing something like that, as well as the random gen nature of most of the gameplay taking place. But I think it can be done in Unity, I seem to remember some other Unity games with decent NPC systems.
