I suppose it depends on what you mean by "unfair". If you mean that it's inherently broken or too hard, then no, definitely not. My first playthrough was exhilarating for the same reason most people said here; it was a welcome increase in difficulty after my character became God incarnate. It's not like it's set up in any way that could be considered misleading; all the mechanics are laid out for you and even the speakers, which most people seem to identify as their major gripe with the add-on, weren't all that hard for me. I've never played New Vegas on any setting other than on hardcore mode, so I also enjoyed the constantly draining health, but it wasn't even that debilitating; with an endurance score of 4 I only lost something like a third of my health while outside. I enjoyed the Ghost People and how you had to make sure they were dead; it adds to the atmosphere of desperate survival and the fact that I was killing them with spears, for the most part, reinforced that even more. What I enjoyed less were the holograms, and that was mostly because I'd somehow convinced myself that the holorifle was meant to be able to damage them and my game was bugged. Honestly, my second playthrough with a combat-oriented character made Dead Money almost trivially easy, even on the hardest setting. Once I found the .308 ammo holotape for the vending machines, I was swimming in ammo. Having to keep survival in the back of my mind even when I was basically the king of the Sierra Madre still made it fun, however, it made it feel earned. However, if you meant for any build that isn't combat or stealth oriented, then yeah, the DLC is kind of unfair. That said, companions in the game are ridiculously strong, especially at Charisma 10, and the ones in Dead Money are specialized in dealing with the Sierra Madre, so you shouldn't really be having any trouble even then; just run like hell during sequences like the Gala and when finding Christine in the suites and you'll be golden. On a side note, the Sierra Madre was where I first found out how easy it is to win at Black Jack in this game; the maximum payout in something in the region of 10,000 caps and I basically consider it an exploit. In fairness, you don't actually get any confirmation that they were lovers.
