At least three of every schematic-based weapon, and at least v.2 on every schematic

That was my first playthrough, anyway.

My second character is three skillbooks short of 100 in everything.

I ♥♥♥♥ LOVE this game.

Oh and I have the Ghoul Mask, too.

As a little apology to Bethseda, I would like to say I enjoyed the game very much.
That is all.

I got Fisto! and Lincoln's Repeater.
Also, Rock-It Launcher is not as epic as it seems.
Shishkebab is... alright. I prefer my Combat Shotgun, which I keep for close encounters.

I'm better than all of you, my friend gave me all the crap he got when he bought the survival edition of the game. :p

Well... I beat it. As an evil ♥♥♥hole.

SPOILERS AHEAD:
My reaction to the ending:
I'm still confused on how some ordinary Colonel was able to survive the rads that killed dad WHEN ENCLAVE TROOPS WEARING SEALED POWER ARMOR DIED THERE TOO.

Also I made Lyons activate Purity, and yet the game still acted as if I had died... don't understand how that worked out, but alright.

Also, I had Dogmeat with me when the Enclave took the GECK, and I couldn't find him afterward. I didn't get a "Dogmeat has Died" message or anything, either. Any ideas?

I've killed 3 of the 5 Behemoths:
GNR, Evergreen Mills, Capitol building.

I took Contract Killer perk, and in case you didn't know, the guy is in the Scrapyard, south of Minefield. Just look in the large shack. Dogmeat is there too.

WHY THE ♥♥♥♥ CANT YOU SEND FAWKES IN (S)HE HAS THE SOLE PURPOSE OF SURVIVING RADIATION JESUS CHRIST THE WRITERS ♥♥♥♥ UP BIG TIME

Remember Sydney?
Well....
"Do de do lets walk right here maybe some loot *kaboom* wtf was that* i turn around and i see a red hand... Ok how did that hand get here... wait where is my help---- shitson.... Oh well, more money for me, and a special weapon too :DD"

I was halfway to the front door when I heard a faint *Bamf!*. For some reason this jogged my memory to talk to Sydney to start that quest to get her gun.

I spent the next 45 minutes searching the Archives for her, killing most of the things that I met along the way.

Had just about given up looking for her when, as I was making for the door, I set off one of the few mines that I hadn't disarmed & stolen. I jumped clear of the blast, and something rectangular with two long strips flailing off the sides flies across the room and hits the tiles with a wet and heavy thud. I run over to it and oh look! A dead, legless archaeologist? Why, just the thing I was looking for!

10 Take gun
20 Exit building
30 Kill dudes
40 Goto 30

- The-Masses

I love the possibilities of the engine. So far I've encountered two awesome random non scripted things - the enclave loving guy from megaton falling off of the roof of his house (what?) and being found dead beside the bomb when I came back.
Randomly exploring near a bombed out church when out of no were a wastlander comes running from behind the church completely on fire followed buy a raider with a lead pipe.

Also I still need to see the behemoth that chases you after you steal his teddy bear

I still haven't heard of bugfixes, so I'm still acting like you are all playing a beta of a game that hasn't been released yet. This makes me feel like I didn't waste my money.
In other news, does anyone sell rounds in DC? I don't want to be in the situation I was in when I stopped playing after the 18th crash in a row, stuck in a mutant-rich zone with nothing but a baseball bat and skills tailored to using firearms.

Rivet City right lower part, Flak And Shrapnel in the marketplace. Has ♥♥♥♥ of ammo and weapons.

I agree about the bugfixes so I stopped exploring the vaults and awesome places so I can do them without having to worry about having to save every three seconds.

Also: I'm wondering which theme I should get for my Megaton house - here's some screens but I think it'll either be Love-Machine (I'm a little worried about one of my parents walking by and seeing the over-hanging "couple" lamp up top) or vault.

Mild NSFW warning on the last picture.

Wasteland Explorer - looks like boring and camping

Raider - awesome and includes a lot of weapons, but guts aren't really what I want to come home seeing.

Vault - looks clean and nice also includes many of the basics (food, clothes) also has a big vault-tec banner

Science - looks clunky and annoying to walk around, it has some chemicals and stimpacks, nothing special

Pre-War - really cosy and nice, also includes awesome intact gnome but not enough items to actually help

Love Machine - Hilarious and warm. Includes atmosphere and plenty of speech impacting clothing and a heart shaped bed.

I would choose Pre-War or Raider, although my suite in Tenpenny Tower is Vault.
