Why is Unity the most popular engine?

lol a unity user today was asking their forum admin to ban me from their forums for the shiit I write here, outside of their forums;
this is internet to a whole new level rofl.

“-Ban him! Kick him out of OUR forums!”

sensitive much…

I think what you mean is that creating a GI solution for Unreal on C++ is much more complicated, thus it feels less flexible. no?!
