Fallout 4 could be set in Boston: rumour

[Graal]

Strange I seem to remember the engine being called "Creation" or "the Creation engine" which is a band new engine that has only been used in Skyrim. Fallout 3 and New Vegas used the heavily modified version of Gamebryo. As far as I know Gamebryo & Creation share some of the same base architecture but was otherwise built from the ground up.

Gamebryo 1.5 was me being sarcastic. Creation was really nothing more than a souped up Gamebryo engine. And it only just managed to not suck as much as the Gamebryo engine itself.

What angered me most is that Bethesda claimed Skyrim was going to run on a brand new engine, yet when everyone started playing they immediately recognised Gamebryo.
