Depends on what you consider to be a role playing game. With so much genre blending and mashups a lot of games have adopted RPG features but I'm not sure that I would consider them as RPGs or what exactly that means anymore. And as far as honestly held but unpopular opinions go, how about this, New Vegas is the worst* Obsidian game.
*I never played the tank game, MMO**, or DS3
**Not sure if you'd consider it an Obsidian game
