At first glance it might be possible to look at Fallout: New Vegas and think of it as nothing more than an expansion to Fallout 3. It uses the same engine and the core gameplay has largely been kept intact, so it does share some resemblance with its uncle. But it only takes a second look to see that Obsidian Entertainment is placing its own unmistakable mark on the Fallout franchise. A new Hardcore mode, tweaked combat, weapon mods, gambling, and a game world as big as Fallout 3 are just a few of the things fans will be raving about up to and beyond the release of this next entrant into the much-loved game series. Obsidian, a development studio founded by some of the same people that created the original Fallout games, is back on the scene in a big way.
