I'm not sure where Plaza de Toros is then, as the Bullring save area is called "Monumental"
Some stuff, this is all before reaching Old Town, so I'll post this for now:
ITEMS:
Rogue Scavenger Gear has an instance of "The Dayglow" in its description, perhaps Gear could be swapped with Jacket since it's a leather jacket with yellow linings
I don't know if this is especifically from Dayglow but I noticed it right now, the Flare Launcher could be renamed to Flare Pistol
CHARACTER/CREATURE NAMES AND DESCRIPTIONS:
Gonzo, the ghoul you're supposed to kill for the church, is named "Madman" if you inspect him, and "Distraught Gonzo" if you hurt him. Perhaps it could be all consolidated as "Gonzo", to tip off the player he's the ghoul he should kill for the quest
In the gas station east to Chula Vista, there are numerous robots that also have the description and same graphics as the border robot from the Bullring, so they should have the "A" at the start too.
Upon inspection of a giant centipede, the Pip-Boy message says "Giant Centipede", it could use an A at the start. Same with the Super Mutants, it's "Hefty green mutant", but it could use the A
DIALOGUE:
The ghoul mechanic in the city entrance could use a little bit of strange speech improvement, both in player dialogue options and his own dialogue. For example, after you speak with him, his greeting dialogue is "Need parts?", while it makes sense since he's a mechanic, I don't think he sells any actual parts, electronic or otherwise...
After getting close to the destroyed bridge, in Route 8, it says "The bridge is destroyed. But with a bit of ingenuity, it won't prevent you from getting down." Perhaps "The bridge is destroyed. But going down is an option, if you're smart about it." could work.
Peck, the ghoul in the sewers below the bridge in Route 8 could use some strange speech improvent. For example, "Don't freak out here, you're on my private property" could be changed to "Don't freak out, but you're on my private property." and "But I live rich!" Could be changed to "But I live well!" or "But I'm doing great here!" or something similar. His "and then go onto the highways" line could be "and from there you can get on the highway again." He also has a line where he mentions "meds" (this being the glowing mushrooms) but in one of his other lines, it seems this is more of a drug for ghouls instead of actual medication
Upon using the crafting station at the mechanic's shop in the city entrance, the Molotov Cokctail is referred to as a "Fire Bomb", there is also an inconsistency in the ammunition section where it refers to regular flares as level 1 flares, while the other options refer to them as just regular flares
After delivering Coffee to the bar owner in the city entrance, he says "I'll make good money with this menu." It could be "with this in the menu."
Upon fixing the MedBot in the hospital, the player's goodbye option is "Oops. I think I have the wrong door." can just be "Oops, wrong door."
Generic Rogue Scavenger dialogue also has "The Dayglow" instances
After rescuing Zerah from the rogue scavengers, the leader will say "Where's that ghoul? Where is he, I'm asking!?" this could be changed to "Where is he, damn it!?" or something similar, the rest of his dialogue could be improved too
Roy, in the Consolidated Aircraft building, has some strange speech, like "Lost your fear?"
Private Gomer (the super-mutant companion in Bonita Dam) refers to the transformation process as the Induction, the mutants at the Inferno referred to this process as something else but I can't remember what, sorry
His dialogue also has some instances of "The Dayglow". After you rescue the Nightkin Captain during his quest, there is also the player line "It's too early to thank." it could be changed to "Don't thank me yet."
Isaac, also in Bonita Dam, refers to Dayglow as "Shining"
After fixing the radio and taking in the next quest, Señor Gustavo has more instances of The Dayglow, he also has aminor inconsistency with Edward (the café owner at the city entrance). Gustavo tells you to go to Edward for supplies, when you talk to Edward, the dialogue option for this is "Señor Gustavo said you owe me some *meds*", perhaps change Gustavo's line to reflect they're meds/chems, after you receive the items it also has a perhaps unnecesary ? at the end of the player response.
If you exchange pre-war money with Edward, he'll just say "Please" as a response after you give it to him. It could be changed to "Here you go."
After taking Edward's food delivery to the dam workers, perhaps it could use some dialogue tweaks after you hand it to the ghouls, change "the food has cooled down" to "The food has gone cold!" or "The food is cold!", stuff like that, nothing big. The Pip-Boy message could also use the same tweak you did at Faro with the sick pescadores, so it goes from (1/5 to 1 of 5)
When talking with the super mutants of Gomer's squad, they say "Let the humans stop hunting us!", perhaps it could be changed to "We want the humans to stop hunting us!" or similar, they general dialogue could use some dialogue tweaking too, but it might be hard to do so since they're mutants and they're supposed to be inarticulate. They also refer to the border guard center as the patrol center, but it could be changed to border center for clarity
A ghoul scavenger appears in the gas station bridge when you kill the robots, he says 'Got a light? There is plenty of junk here, but fire', "but fire" could be changed too "but it's dark."
If you talk to the ghoul in a black suit next to the craps table in the Little Italy casino, one of the player dialogue options is "Ignore it", it could be changed to "[Ignore him]"
The casino administrator, Albert de Santi, could also use some general strange speech checks
WORLD OBJECTS:
The steel beam at the end of the destroyed bridge in Route 8 is referred to as a Railroad Tie, upon inspection it says "Fragment of a bridge frame." It could use an "A" at the start.
This also isn't Dayglow exclusive, but the steel doors you find in sewers are referred to as "Manholes"
The Mentats Vending machine mentions you can "hack it", you need to use the repair skill to open it so perhaps it could be changed to "unless you intend to open it with a technical approach." or something similar
If you try to use the holographic emitter, it will say "It doesn't respond at all" perhaps add a "Perhaps its power source is around here." or something similar, to tip off the player to look around a little, I don't know if this is necessary though
After unlocking the safe in the gas station to the east of Chula Vista, it says "You unlocked the door", but its a safe
Upon inspecting the Auto-Doc in the hospital, there is a typo, "adminster"
After shaking down Zerah and he confesses the money is in the mailbox at the entrance, after opening it, it says "there were pre-war money in the mailbox", were could be swapped with was
After approaching the Café area to the west of the Hospital, there are two blocked roads to the north, the Pip-Boy message says "The road ahead is blocked by building collapses", building collapses should be switched to "collapsed buildings"
The radio station in the town hall also has an instance of "The Dayglow" after you repair it
