I'm late as hell to playing through it but I'm currently playing through Fallout NV along with all of the DLC, I've already played through the main story before but I never actually played any of the dlc till now, really only been disappointed with one of the new stories i've played through because it's too linear for my tastes. >__<
I think it's great so far, as well as interesting. But I didn't get very far and have bad concentration issues lately so I haven't gone back to it yet. u.u Even outside of the original world though it still has a very "bioshock" feel, which is nice.
