A. Song choice:
I prefer "I don't want to set the world on fire". I actually love that song and found myself singning it at work. But here, it's a matter of opinion as the two choices are solid.
B. "War" Speech
FO2 didn't spell everything out? Check it out again. It told you everything that happened since the Beattles started smoking pot... Fallout 2 may be better, but not by that much.
Character Creation:
Definitely interesting way to do it, from being a baby. Gets old on the 5th playthrough but still interesting.
Graphics:
I felt FO3 did a good job of making the world unique from Tennepenny Tower to Megaton, From Cantenburry Commons to Rivet City. From The Republic of Dave to Underworld. From Oasis to Girdershade... okay scratch that last one. It's not a town, it's neighborghs. These are different towns with different feels. Fallout two was better, but not by as much as you make it.
BoS
In Fallout 2 they want to you get Vertibird plans. In Fallout 3 they want you to get a geck. I agree with the power armor being too easily handed out, they could have made it that you need to do a mission for them but, again, they aren't as far from each other as you say.
Enclave
Okay, Encalve sucked. I agree. They had cooler weapons and deathclaws and Sentry Bots with them but that was it. The main reason they were a threat was that they were helped by robots and killer walking... crocodile things...
Ghouls
Ghouls weren't part of every towns in FO2 and they are more important than you make them look like in Fallout 3. Underworld, which is where you find Reiley, the Tennepenny tower quest which had a different view about how ghouls and humans would treat each other but doesn't make it less present.
Super Mutants
I am still looking for the reason why mutants are in DC. My bet is that we'll find out only in a DLC. And honestly, if every SM was a SM Master from the beginning, it would have been better. Fallout 2 was better in that.
Humans
You are right... in FO3 every human is the same. No evil or good characters here. Are you kdding me? Maybe there was more memorable characters in your mind in FO2 but open your eyes. There are good and evil characters in both games. Hell, your NPCs will be determined by your Karma since they are either good or evil.
Monsters and Others
Ennemies from FO2 NOT in FO3: Rats, Geckos, Radiscorpions, Wamingos, Plants, Exploding Brahmin, and plenty plenty plenty more. Different creatures depending on areas and some that can be found everywhere.
FO3 - Feral Ghouls, Mire Lurks, Giant Radiscorpions, Yao Gai, Flies, Roaches, New types of Robots and Behemots.
Yakuza are raiders with swords. Slags aren't ennemies if you do the quest peacefully just like Tennepenny Tower Residents are hostile if you don't enter the ghouls or attack them. It wouldn't change squat if they called some raiders "bandits" or "mobsters" they ARE the same ennemy. At that rate I would have prefered something from FO Tactics: Beastlords. People who trained various animals to help/fight for them.
Difficulty
No argument there. FO3 is way too easy for my tastes.
Story
This is the biggest mistake people make when comparing the game. FO2 is open ended? How? Let,s get back to the MAIN quest. Get out of your nest, try to find Vic, free Vic, get info about Vault 13, get a geck, get on a boat and kick the Enclave ass. There is no way to do it otherwise. Everything else are side missions. What made Fallout 2 better was that side missions were included in the ending.
Basically, you need to see Arroyo, Klamath, The Den, Vault 13, NCR, Vault 15, Vault 13, San Fran and Oil Rig. The most interesting places aren'T on the list...
Fallout 3 goes from Vault 101, Megaton, DC, Rivet City, Vault 112, Jefferson, Citadel, Little Lamplight, Vault 87, Raven Rock and back to Rivet/Jefferson for the finale. Again, some of the most interesting places aren't on the list.
Dialogue
Again, you think with your heart and memory. Fallout 2 had many many dialog trees that would amount to nothing. It also had a lot of totally useless information. There was better dialog writting but in both games you have dialog trees that are good and some that amount to nothing.
I also LOVE how people bash Bethsada for not following the Fallout logic while Fallout 2 was full of references that happened after our worlds "seperated". I liked them, but they don't make much sense.
Conclusion
Fallout 2 and 3 are different beasts. But at the heart they feels very similar. A wasteland to explore with a somewhat short main mission but the meat is in discovering the rest. All the side missions, the other cities and so on.
I hope someday Fallout 2 players will take a real hard look at both games and realize they aren't as far off as they claim it is.
