Reinstalled FO3 after several New Vegas runs with a relatively short mod list. Unofficial patches, weighted ammo and consumables, bobbleheads begone etc. Oooh boy. The story of Lonewanderer Middleagedguysson (19) is as good as it was a decade ago.
1. RNG based speech checks are red tip on a blue pen retarded. You have about 20% chance to succeed certain lines even with max Speech. I bet some Bethesdard still defends the system to this day as it provides "replay value". I bet the very same Bethesdard is also against quick loads as it's "save scumming" and load times are long on his console.
2. Megaton, Rivet City, Tenpenny Tower, The Republic of Dave and Little Lamplight are all shitty communities that don't make sense whatsoever and shouldn't exist in a wasteland with scarce resources for more than 30 seconds. Karma vendors outside cities fucking suck. I wonder if Barter changes the purified water/karma exchange rate.
4. NV is also guilty of this but in FO3 is a lot more pronounced. DLC gear is unscrupulously far superior to vanilla gear. Now you may say they are meant to be better than vanilla items because of release dates, but some are outright broken. There are several examples but the biggest offender is the winterized variant of T-51b with high durability. Bethesda accidentally gave the player the simulation variant that doesn't need repairs but never fixed it. How convenient.
5. Broken Steel's retcon of the stupid vanilla sacrifice wasn't written after fan feedback. The "two weeks later" video was there in the game files all along, before they released said DLC. Some of you may remember this.
And this is without getting into the worldbuilding, Emil's wonderful dialogue lines and quests.
The game is only good for taking a hike in the greenish rubble and shooting stuff.
