This, this, this.
I think the argument about the low percentage of people having finished the game in hardcoe Mode is also stupid because it doesn't take into account all the people who played most of the game in that mode, but just happened to switch to the normal mode a couple of times. Or all the people that played hardcoe Mode for hours and hours but didn't happen to actually finish the game. For example, I only actually finished NV once (even though I did about 3 or 4 full playthroughs where I did most quests and found most locations).
