From cinematic kind of view... best FNV DLC so far, imo. The landscape looks nice and the generic effects are better than I've expected. A few new armors and weapons with ammo types, etc. Enemies are pretty tough, imo.
But it's very linear. Okay, not a big surprise if the DLC title already hints towards "road." As far as I can see, there are no real side quests. You are moving from one area to the next, to the next, etc. and explore the surrounding while this. After every step you have finished, there is a short break where you talk with your companion npc. It is also very much a shooter-DLC, more than in the other DLCs. At least it feels like that. Lots of explosions and stuff to kill with explosions and explosions in the sky, etc.
I am approx halfway through it, I'll guess. Will continue tomorrow and then probably finish it. Have to say, if I'll ignore the non-existing quests and stuff in LR, it is probably my most liked FNV DLC already.
/Edit: Ah yes. LR also doesn't start with a intro slideshow. Due to this, it feels very connected to the Mojave area. You go to the car barricades in the main game, and start the DLC right behind them (switching to the DLC territory). This way, it really feels like you are walking the road to your target and don't get teleported first, to start your roaming after, etc. This fits.
