I'll reply to this if you don't mind Kai, even though it wasn't directed at me.
It's funny, because when I played Fallout 1&2 I always thought how much cooler and immersive the games would be if they were more like Daggerfall. Well fortunaly my wish came true.
More immersive, yes, but Fallout wasn't about immersion was it? In fact very few RPGs (and they've all been created in recent years) are for immersion. Any game of any genre can be immersive, it isn't a main point for an RPG. So while FPP/TPP will make (and made) Fallout more immersive, that was never the aim of the developers who created the Fallout series.
Alright first, Combat in the old Fallout games was pretty skillless and not good even for a turn based game(X-Com or JA2 this is not). And, what exploration? Fallout1's world was to tiny, you could fully explore every nook and cranny in just a few hours. Also, as has been mentioned before, both games only had a very few decent dialogues. On the contrary, Fallout 2's dialogue was pretty atrocious in several situations and immersion breaking.
Combat is pretty simple and straightforward in Fallout, which is why I wouldn't call it a nuisance. The aiming system is the only tactical part of the combat, and I think it's very well done. Fighting against a village IS boring, I'll give you that, although when do you actually fight against a whole village? I can only think of one option where you were forced to fight against all the regulators in the Boneyard.
Fallout 1's world is tiny, but there is a lot going for it. Quality > Quantity. Fallout 2 on the other hand took a different approach, Quantity > Quality. Granted that I loved both, I prefer FO1 over FO2. FO1 really felt racing against time, as well as the characters were more interesting and the plot was quite good, the Master's character being what I loved best (although the final dialogue with him was a bit disappointing, I wanted it to be longer in order to convince him otherwise).
Fallout 2 was filled with jokes, gimmicks and New Reno. I agree that it felt out of place.
Granted, there is a lot more combat in FO3, but it is actually entertaining and not a nuisance like in Fallout.
Like I said before, I never felt it was a nuisance bar fighting against a whole town. But FO3's combat never felt entertaining to me, not at all.
No interesting locations in FO3? Well how about Tranquility Lane, which reminded me of http://en.wikipedia.org/wiki/I_Have_No_Mouth,_and_I_Must_Scream. And the Dunwich building was a whole lot more scary then the Glow ever was, the audio recordings were just freaky.
And interesting enough, I was horribly dissapointed the first time I saw http://images2.wikia.nocookie.net/fallout/images/4/40/Fo1_Necropolis_Halls_of_the_Dead.png, since I had expected something less....generic. http://images4.wikia.nocookie.net/fallout/images/c/c6/Underworld_Fallout.jpg is pretty much how I always thought it should look like.
Can't agree on this. First off the Glow is on of my favourite locations in all the video games I've played. The eerie place, the radiation, finding information about the whole ordeal, revealing another piece of the puzzle....and most importantly it was optional. No one forced you to go deeper inside the Glow. It was just interesting enough to do so yourself.
Whilst Necropolis was nothing special (apart from the super mutants where I suddenly [censored]ed my pants the first time I met with them), Underworld is pretty much the same, although sillier (barber?). Both were pretty average.
