As I said Creation Engine did mot stop another studio from being creative.
They are not being hold back by Creation Engine in game design, they are stuck in a design philosophy and production strategy that until now has and got them lots of praise and sales.
They use the chest trick because saves reworking the inventory and container system. That would take time and left the game almost the same, so they don’t.
If they used Unreal engine they’d have to build a new inventory and container system from scratch, who knows if they would end up taking the hidden chest idea (it mostly works) and porting it?
The “Update your engine Bethesda” discussion is valid from many points of view, but most of the problems with current Bethesda releases are cultural. They don’t test nearly enough, they don’t have a “fun” game until a couple months before release, they don’t coordinate the content and mechanics production in any way, the quest writing is a free for all.
And until now things worked out. So they refuse to address those issues.
Not being intended as a joke makes it even funnier. I mean, the lack of awareness is amazing.
