Yes, it's undeniable that the development team has provided a wealth of Points of Interest (POI) and a vast array of building blocks, making 7 Days to Die exceptionally rich in its construction aspect. However, the game is not limited to being solely a building game; it also encompasses RPG and survival crafting elements. Unfortunately, these two aspects are currently lacking considerably in content. While mods can certainly contribute to filling this gap to some extent, relying on mods alone isn't a sustainable approach. These elements should constitute the core content of the game and shouldn't be delegated to third-party developers. This is 7 Days to Die, not 7 Days to Die: Darkness Falls, Sorcery, Rebirth, or similar mods. Moreover, enhancing the richness of the game's core can also facilitate greater potential for mods to flourish.
By "unique items," I refer to specific items that can only be obtained through interactions with Traders or by exploring designated areas. These items should assist players in progressing to the next stage of the game, such as certain workstation tools or components of weapons.
Currently, the game is structured with only four stages: Stone, Scrap, Iron, and Steel. Players can rapidly acquire a wide range of endgame equipment through Traders. In Alpha 21, you might find that despite your crafting skills allowing you to create basic handguns, you've already obtained an SMG through quest rewards. The issue at hand is the scarcity of game stages and the exceptional quality of Traders' rewards, isn't it?
