Fallout 3 was Oblivion with guns. This game is a shooter at its core, with some light Assassin's Creed styled side events and collectibles to find. --- "I'd rather betray the world than let the world betray me." -Cao Cao
Apart from having less crafting etc etc. The openworld thingie is pretty much the same apart from the fact that you have to reach some points to gain a bit more vision, then take others to make it safe etc, so in that view its not really the same, Skyrim was more open to where you could go where you wanted right of the bat, this isn't that much.
