I really don't know much about engines so please be comprehensible.
I've always read good thing about Unity. How it's easy to learn and how it's still very competent despite being very simple to use, etc. Is it actually on par with a big engine like Unreal for small studios? I imagine big studios with big projects are better off with Unreal Engine, but is Unity still king when it comes to the indie scene or just as a "first" engine to learn.
I'm asking because I will need an engine to work with in the next couple of months to work on my portfolio. Which is easier to get into, while also not being useless to learn in the long term?
