We'll start with Ed-E and Veronica as they're the two that are currently carrying all my stuff as I pave the way for the NCR revolution.
Ed-E
There's something poetic about a girl (I'm a girl in this playthrough) traveling the wastes with the robot she found and fixed up herself. Even better that the aforementioned robot starts playing old Envlave audio logs every few days or so. Is that sinister or is that sinister? (hint: it's sinister)
It's also nice to just have a giant robotic bubble watching your back. Just program the thing to shoot from a distance, take one shot at whatever you want dead, and Ed-E will just laser snipe the thing till dead.
Having a robot also helps keeps me from feeling too bad from the absence of judgmental eyes staring at me.
Score: 4 of 5
Veronica
If you can get past her straight up lying to you when you first meet her, Veronica is a pretty cool companion. Definitely spent my time as a male in this game trying to impress her... I guess I'm just a romantic at heart. Too bad romance doesn't really exist in nuclear apocalyptic wastelands according to Fallout. -sigh-
The Brotherhood of Steel remains one of the coolest factions in the Mojave Wasteland and having one of them on your side is certainly welcome. It also might be beneficial to say that Veronica goes crazy with her Power Fist. Like she kills... everything. To put it in perspective, I pissed off the Highway Fort that I picked her up at resulting in 20 people attempting to kill me. After running a bit and killing 2 of them, I looked back to see her successfully punching the heads off of 15 of them...
You definitely earned that dress that you've been asking for.
