I've been seeing Bugthesda fanboys defending the Creation engine (or as I call it, the Cremation Engine 'cause it's a hot mess!) saying shit like "Well the Unreal engine is 20 years old and blah blah blah" but they're missing the point. No one would care about the age if the engine got more polished and more robust over the years. Except it hasn't. While Bugthesda seems to add bigger worlds and more features, the games just seem to get buggier and buggier.
What I wanna know is, why? Is it sheer laziness or is there something inherently deficient with the engine? Like how does something like the Unreal engine work "under the hood" in regards to level creation, hit detection, physics, AI, NPC pathing, scripting, etc. as opposed to the Cremation Engine?
