Do we really need DI frameworks like Zenject/VContainer in Unity? What problem are they actually solving?

I've been seeing Zenject, VContainer and similar DI frameworks being used a lot in Unity projects. And honestly, it sometimes feels like if you're not using one, people think you're doing something wrong or that your architecture is "weak."

But here's where I'm confused:
What problem are they really solving in the context of Unity games?

Unity already allows us to assign dependencies via the Inspector — which is essentially manual dependency injection. You hook up the components you need from the editor. So in many cases, DI already exists by design.

Even when connecting different systems together, I rarely see a situation where one system needs to know about the entire other system.
For example, if I have an enemy spawner that needs to know how much time has passed, it probably just needs a float value — not the entire TimeManager object. Passing in the full object feels unnecessary.

Instead, I often prefer a data-driven, layered architecture — where systems don’t directly depend on each other, but rather on shared data structures. This way, things stay loosely coupled, modular, and testable without relying on a DI framework at all.

So my question is:
👉 When is a DI framework like Zenject or VContainer actually worth it in Unity?
👉 What kind of problems or project scale truly justifies using one?

Would love to hear from folks who’ve used these in real-world projects.

What would you love to see in a top-down game?

Hey folks!



I’m working on a top-down game (Unity-based), and I’d love to hear your thoughts. I’m keeping things lightweight and simple to start, but I want to build something players would actually enjoy.



So here’s the question:



What do YOU want in a top-down game?



Not visuals or polish — I’m talking gameplay:



What kind of style do you enjoy?
What’s the “fun thing” that keeps you coming back?
What sort of features or systems do you wish more games like this had?
Or even—what top-down games have really stuck with you and why?





Just brainstorming with the community and hoping to build something cool

Appreciate any ideas or insight you’re down to share!
