I never got the hype of New Vegas (and 3D fallout in general), it always felt like you were map painting the region to a level that was unrealistic for most individuals who werent nearly deity-like. The hardcore mode also didnt feel survival-y enough, just more meters you have to micromanage.
I do like the world and some of the writing though (The hearts of iron mod feels like what Fallout tactics should have been.), I also think being able to viably do unarmed runs is really cool too.
