What was the worst decision you made in FO3 and FNV?
In FO3 I let Sarah lyons die in the end game.

For FNV I really haven't made a decision that I regretted.

Oh that's hard. I think letting some people die in that village getting attacked by super mutants in FO3. (The on with a rope bridge)

Hmm I would have to say in FNV first time I played I sided with the legion as I thought they were cool then i regret it soo much when I got to Nipton.

my worst decision is thinking that there was only one deathclaw and decided to shoot it an find out that i was completely f%@#ed

In FNV, I decided to help all factions at once in the war, no saving, the legion and the ncr both ended up hating me.

DoubleTripleQuadruple Agent fail

Helping the NCR get to end game. I preferred the independent ending.

Probably killing Mr.House. It's funny I always say I'm sick of him and want to pull the plug but when I see his frail withered body and once I get that note that says Mr.House is dead I kind of get emotional in a way hah, like I actually killed a real human being who had purpose.

Heading to (or at least attempting to) New Vegas though the death claw mating ground or whatever it was called. Got rekt instantly.

My bad. Didn't realize this was on enb. Posted this on my phone, but thanks for the notice.

Most of my terrible decisions usually start with "this is a totally survivable jump," but for worst decision I would have to say the one time I blew up megaton trying to do an evil playthrough. The explosion hadn't even finished before I was overcome with guilt. I just couldn't keep going after that, deleted the save and never tried again :\

I feel ya metallic. I felt guilty but then i'm just like I don't think it will effect me later on in the main quest. (I was wrong.)

worst decision ever while playing fallout NV would probably have to be when I first got the game and I decided to take on the Bison Steve Hotel full of convicts with only a almost broken single shotgun. And when I managed somehow to kill everyone in the hotel I found deputy beagle and shot him because idk to be honest he just scared me and i killed him. Then all the primm residents got pissed off at me for killing their useless deputy and couldn't progress the mission and worst of all is that I only had one save and I would always overwrite my save file.. so I had to restart from the beginning

The worst decision I ever made was when I was doing an evil play through in FO3. I decided to be a jerk to everyone in the vault and it made me feel like a serious douche. Or when I saw Moira after destroying Megaton.

I made my character super ugly which as made the game very amusing, but his head is so big it pops out of the armor and ruins the immersion.

The worst decision I ever made in FNV is to choose the plot line in which I helped Mr. House. Exploring different places and reading notes from terminals learned that hides the past and this character until I was stupid, I was helping such a selfish asshole who thinks only of power and profit, and knows how to sacrifice everything for this.

Forgetting to make a backup save before going absolutely ballistic on the entire world of NV. I obviously learned nothing from my mistakes cause I continued to do it. Replaying that intro sequence for the umpenth time really got to me after a while.

Making a bad looking character back in my first playthrough of fo3 back when i played it on the console. This was prior to knowing about the existence of the face changer so i ended up just remaking my entire char after getting a decent amount of progress in the game.

Biggest mistake was when I went AWOL after I just decided to f*ck around and I realized autosave was on and my game that was saved on was on the autosave, so it saved over it and I had to restart!

Helping Roy Phillips in fallout 3, even if you let them move in peacefully they end up killing all the humans anyways. Seems like a huge waste, even if the residents are jerks they don't deserve to be massacred.
