Question: I've seen people wanting SPECIAL to be 'like it was' mind you I haven't played the first two Fallouts, but how exactly did SPECIAL work before? I can't imagine it having that much of an effect on gameplay (or at least Fallout 3's system)
Basically, it just had much more impact on the game than it does in Fallout 3. In many ways, the character creation defined a lot of your playthrough and your character. In Fallout 3, I can win almost all fights on my own using weapons that I have put no skill in. This is not the case in the older Fallouts. In Fallout 3, it's also possible to max out quite a lot of your skills over the 20 levels, and even moreso using the level 30 level cap. Again, this didn't happen in the older Fallouts. In Fallout 3, it's very easy to not only be a jack of all trades, you esentially become a master of them.
Another example is like UnDeCafIndeed says, if you have a low Intelligence, that will be reflected in your dialogue options and a lot of the game will be completely different.
I'm not saying that the older games were perfectly balanced, because they were not. But, given how important the character creation and SPECIAL system is, it was much more pleasurable and possible to create a unique character. If I never put points into Energy weapons, then I'd get slaughtered if I tried to use them. Whereas in Fallout 3, you can use most weapons effectively (or effectively enough to kill any foes).
