I can agree with the Bioshock feel, even certain Wildstar feel, in the aesthetic and humour. But I don't get the Fallout vibe, I think people are just too eager to see Fallout in it because it's Obsidian making RPG with shooter gameplay elements. Either way, doesn't matter, Fallout has gotten worse and worse with every installment, something fresh that doesn't remind players of that is probably the way to go, and I'm sure that's why they've veered clear from a post-apocalyptic setting for this game.
The actual gameplay is what I'm interested on. The setting I'm not sold on, but if the story is compelling, the mechanics are solid and the game more of a RPG than a shooter with skill points, then I'm sold.
