Well, Fallout: New Vegas feels like Fallout 3 to me (Bethesda), and feels completely different to Divinity 2. Either way New Vegas was clearly influenced in a big way by the way Fallout 3 was developed. IMO Fallout 1 & 2 were both superior to Fallout 3 & New Vegas, regardless of the fact that some of the original Obsidian developers worked on it. I could go into detail as to why but it would take too long. I must admit I thought that Divinity 2 used an inhouse engine, so it surprises me to find out they used Gamebryo (thanks!). Well I guess it just shows Larian know how to make better use of it than Bethesda!
