I found him early on, then spent the next hour trying to level up to repair him. But then I later realized the parts to fix him are scattered in the room with him and I felt real dumb. Lily's great too, but when her quest came up, it reminded me of my own grandmother (who had recently died) and I couldn't bring myself to put her in harm's way anymore so I left her at the hotel from then on.Old World Blues is great, tied for my favorite with Dead Money. If you get the chance I'd recommend them all, but word of advice; avoid radios like the plague in Dead Money, they will kill you in a snap haha. The modding community for the game is insane, it's gotten to the point that you can mod in multiplayer and actually have it run pretty decently. I only finished 3's main quest once and haven't played any of it's DLC, it didn't hook me like New Vegas did. Fallout 4 is pretty good too, it's something of a halfway point between 3 and New Vegas in terms of gameplay. Storywise, it's not connected to either and you could jump right in.
