The thing about a 1-10 scale for SPECIAL is that some people may infer that a SPECIAL of '1' is truly awful and a SPECIAL of '10' is awesome.
It stands to reason because '10' is er 10 times bigger than '1'... duh...
But when you look at what carry-weight (Strength), hit points (Endurance) and action points (Agility) are accrued by selecting between 1 and 10 SPECIAL points, the real increase you get (or more particularly don't get) is quite a surprise (at least it was for me).
And I'll give you the punchline before sharing the stats, carry weight only increases 40% from 1 to 10, Hit points (health) only increase 50% and action points basically double in number from 1 to 10.
If you run with a Strength, Endurance, Agility build of 1,1,1, you are certainly weaker, but you are not a weakling, simply by virtue of SPECIAL..
This means that SPECIAL choices at the outset of the game are all about the perks that you can access, and keeps a very wide variety of SPECIAL choices viable.
(Using http://vault111.com/?page_id=21 calculator)
What increase in STRENGTH actually gets you (in weight):
- 1 Base (210)
- 2 +5% (220)
- 3 +10% (230)
- 4 +14% (240)
- 5 +19% (250)
- 6 +24% (260)
- 7 +29% (270)
- 8 +33% (280)
- 9 +38% (290)
- 10 +43% (300)
What increase in ENDURANCE actually gets you (in hit points):
- 1 Base (85)
- 2 +6% (90)
- 3 +12% (95)
- 4 +18% (100)
- 5 +24% (105)
- 6 +29% (110)
- 7 +35% (115)
- 8 +41% (120)
- 9 +47% (125)
- 10 +53% (130)
What increase in AGILITY actually gets you (in action points):
- 1 Base (70)
- 2 +14% (80)
- 3 +29% (90)
- 4 +43% (100)
- 5 +57% (110)
- 6 +71% (120)
- 7 +86% (130)
- 8 +100% (140)
- 9 +114% (150)
- 10 +129% (160)
Just by this anolysis, if you prefer to use VATS, just on the numbers for example, you're better off favouring Agility over Endurance because 6 points of Agility get you an extra 71% action points to kill things approaching you, than the same 6 points allocated to Endurance giving you less than 30% extra health protection if those foes reach you.
The thinking process at start becomes - which perks do I want (in order)?
and which SPECIAL ranks facilitate those perks.
Not, how strong, agile, or enduring do I want to be?...
I don't know how Perception, Charisma, Intelligence and Luck upgrade (someone may know), i.e.
- Proportionately how much more aware / accurate are you with high Perception?
- Proportionately how much more charismatic are you with high Charisma?
- Proportionately how much more experience do you gain with Intelligence?
- Proportionately how much better is the loot / more frequent are the criticals, with high Luck.
Charisma is particularly interesting as the ability to talk yourself out of a situation is rather binary, you do, or you don't.
(the same may apply to lock/safe picking and hacking)
Anyway, sorry to ramble, I'd be interested to know what you think
