...and so all of this changed the game how? Didn't. You still killed animals, bought some rat on a stick. The effectibe change was to force you to hit a button periodically. It didn't change your approach to the game in any meaningful way. In addition to the sheer stupid boredom of it that was the gravest failure of the mode. It was the same game just with a bit more administraive overhead tossed it. More management, no more depth or interest but plenty of people confuse complexity and depth.
I confuse nothing. It may not have changed the game for you, but it did for me. In hard mode everything had weight so the gamer had to keep track of what was being carried and how much of any ammo could be carried for the arms the character had. When it was better to use a melee weapon and conserve ammo. The character could become addicted to chems. It affected what perks would be taken depending on playstyle.
I like resource management and all that involves. Planning out a campaign down to the minute details is fun for me and others on this forum even if others disagree.
For those who did not wish to do the hard mode in FO:NV there was the easier mode.
I cannot wait to see what the final versions of Wasteland2, Pillars of Eternity along with a few others coming out bring. I am playing Might & Magic Legacy and Eschalon Three (good use of food, sleep and drink) right now. I just finished a run of Kingdoms of Amular which had a sleep mechanic (which should have been better implemented). Eating and drinking would have been welcomed.
It adds to the immersion for me.
