Maybe playing it again will make you notice the following.
That Power Armour is a joke without damage threshold.
Also, do not forget that the player, in Power Armor, will only be able to move as fast as an asthmatic snail, whilst NPCs can sprint fast while wearing the same Power Armor as you. That's right. NPC Encumbrance is STILL just as broken in FO3 as it was in Morrowind and Oblivion.
How you can do something super evil like blow up Megaton and how no one knows (no reputation system)
True evilness in FO3 is not merely broken, it is unplayable because the devs designed FO3 so being a kleptomaniac and psychopathic murderer is as good as it gets for playing evil.
The player is even forcibly told that certain things that the player does are evil, whether or not what the player's character WOULD see those things as being evil.
EG: inhuming intelligent ghouls. For a player who is wanting to help the Enclave clean up America, inhuming ghouls is just part of cleaning the filth out of the DC wasteland and making it safer for proper unmutated Humans.
How broken the economy is seeing as you don't need to buy a darn thing.
For the bulk of what you find, you can never find enough traders in one area to offload the junk onto.
And along with that is scrabbling to find certain gear so you can try to get yours up to a useable condition. And just to make things that much more difficult for the player, traders can't repair your gear to perfect.
How you can't really talk your way out of killing
The concept of peaceful solutions to missions was infrequently explored in Morrowind. What there was received heavy excising for Oblivion What little remained was nuked nearly to obliteration for FO3.
Can't join many of the factions, can't even talk to any of them.
The same defective game design regarding factions that was in Morrowind and Oblivion, was bitterly complained about for the same, was once again inflicted on gamers with FO3.
The idea that the player might want to play the game on the side of the 'opposition' is never permitted.
The idea that the player might want to RULE is actively prevented.
Shades of morality are to be avoided at all costs. All factions MUST be pure good or pure evil, and the player MUST do the MQ for the Forces Of Justice And Good And Right.
How there is no real challenge thanks to the amount of level scalling.
When Bethesda made Oblivion, they got slammed by gamers because they overcorrected the problems from Morrowind. They tried another idea for FO3 and it as well has failed, dismally.
Making a specialized (RPG) Character is very hard to do without making a character with very low special. Become master of everything very fast.
Bethesda's games are ones that demand a Jack Of All Trades character whose skills are well above average just to stand a chance of survival, as single player non-co-op is their forte. The 'companions' you do get foisted upon you invariably turn out to be frustratingly defective in how their AI operates, to the point where all you want to do is to actively inhume them. So as a consequence, unless you like a playing with gimped a character, you HAVE to get your skills maxxed out ASAP.
