I'll give this a shot (without trying to get into a "this one's better than that one" sort of debate...)
If you called FO3 working your way up from the dirt, to a god what would you say about the first two?
I had more of a sense of this in Fallout 2 than either of the other two games, to be honest. Simply because you start out at pretty much literally rock-bottom. In that game, you're going to be glad you spent the time doing the quest that gives you a
sharpened spear; and early on you're going to treasure even a pipe gun and hope you can keep enough ammo around to keep it working. The beginning of that game really felt like it was a struggle just to survive; and left you making some really tough choices.
It's easy to be the good guy and take the high road when you're sitting on top of a mountain of stimpaks and bristling with weapons - it's much more meaningful a decision when you're bruised and bloodied and looking for a couple of caps just to buy some healing powder (which isn't as good as a stimpak - which you can't afford, anyway - and lowers your PER on top of it.) I'm also just a fan of the item progression ladder in that game - I think it was very well-balanced, where you spent a decent amount of time at each tier of climbing towards the "best" stuff in the game.
If you said the Further along in the game you get, The less important charcter creation becomes, what would you say about the first two?
Character creation is probably the most important choice you're going to make in Fallout 1 and 2. Arguably too important, considering you're going to have to live with those consequences for the rest of the game. It can be a downer to make a weakling character, only to find out a few hours in that you're never going to be that great with anything heavier than a pistol (at least until you get enough skillpoints in to negate the negative modifier.) But yeah - a character with 100 in all skills (which isn't that terribly high in the previous two games,) and drastically different attributes are still going to play quite differently; as opposed to Fallout 3.
That feeling you get when playing FO3 for the first time that normally dies by the time you find lamplight, if it lasted say 65% of the story, how far along in your first play through in FO and FO2 does that feeling last?
I guess that depends on what feeling you had playing Fallout 3 for the first time, that died by the time you found little lamplight...
