Larian's engine being very limited in the things it will allow is a huge factor in a lot of the issues with the game that have been brought up in this forum, such as day-night cycles, the chain movement mechanic, proper reactions, no pause during real-time exploration, etc. But that engine is what allows for all those "cool" things in the game, such as elemental surfaces and pretty graphics, and those things are what matter most in Larian games.
