" Depends on how many bullets it will take to kill something, dying easily I can deal with and enjoy the challenge, always loved RPGs that require food+ water managment... but if you're dying because an enemy takes 20 shots to the head, that's not fun and I might wait for a second playthrough. "

I'll be playing on the hardcore setting, assuming that I can independently alter the difficulty of the game.  I like the idea of the more realistic weight management, though now I'm bummed out that I won't be able to carry 10,000 rounds for every gun where ever I go. 
 
Does anyone know if the shooting mechanics in New Vegas have improved?  I'm hoping for more for the CoD/Borderlands way of gun play.

" I'll definatly try to have a playthrough on hardcore but if theirs no acheivments for doing it  then I wont since I dont feel like going through hell for nothing. "

I don't want the enemy having more damage advantage... but I would definitely like the water & weight difficulty options added to my playthrough.

not til i beat it on normal.

If there's achievements tied to it, you can bet your sweet ass that I'll be playing it.

Yep my 1st playthrough will be normal difficulty - hardcore mode. I was hoping Fallout 3 had a mode like this so I'm pretty stoked for it.

There's a fine line between fun and punishing. Hardcore sounds cool, but also very exhausting - to either live with your consequences, plan way ahead of time or reload every 10 minutes. To me, Fallout 3 was my "chill out" game - I would play absent-mindedly while listening to music for hours at a time. I'll probably try it, but I highly doubt I will last through the whole game on that setting.

According to steam there is an achievement... i am telling myself i will play it like that but i don't want to quit 1/4 of the way in and have spoiled the beginning of the game for myself.

maybe.. fallout 3 was very easy on very hard

I'm going through it on normal first. If the game is good enough, I'll give it a try on on Hardcore.

On my second playthrough I probably will (If I get the game). ACHIEVEMENTS!

nope.

no.

I'll most likely play it on hardcore.
