I think that I can claim to be fairly experienced in Fallout 3 with character-building and such, but I'm new to the original Interplay games. I've played a bit, but I haven't gone at all in-depth yet. So I'm just wondering -- how different are the stats? Not as in differences in the system, but differences in how valuable skills are.
Some specific questions: In FO3, Intelligence is important because it allows you to level your skills more per level. Is it the same here? Agility is not so important in Bethesda's game because, although VATS is important, a low Agility can suffice, so other attributed can be increased further. In the originals, AP are actually used to move around and perform actions in battle, so is Agility therefore more pertinent? In FO3, Intense training and the bobbleheads can greatly raise your attributes (and potentially max them out if you forgo several other perks). In the originals, is this true, or do your SPECIAL attributed more or less stay the way you assign them in character creation?
I'd ask more, but I'm the type of person who could write a book of questions about any given subject. If someone could just answer some above questions and perhaps offer other significant tips and/or differences between the two statistic systems, it'd be appreciated somewhat.
All SPECIAL stats are all valuable in the earlier FOs, but it depends on how you want to develop your character. Intelligence is generally important for all characters, especially if you want a character capable of talking.(IMO). I find that Agility is more valuable for characters who have lower endurance (Ability to run, get out of range, or kill them before they kill you). Endurance and Strength works in basic rpg sense, health and resistance while strength deals with damage output for melee, how much you can carry, and other factors (Note, heavy weapons tend to have Strength checks). Perception can lead to some humorous situations as they can effect your examine descriptions, the description you get when you first enter a town, etc. And some perks will raise your SPECIAL/Skill attributes but I believe most of them are temporary increases for certain situations.
Also, for character development, you'll want a form of balance. Having a skill at 1 will generally lead to some complications later in the game, I generally don't place any attributes under 4. And finally, the best choice is experimentation. Don't be afraid to reroll your character and start again. Hell, after playing both games multiple times, I still find myself screwing up in character creation and restarting...even though it tends to be rare after your first few characters.
