Is the basic assumption of this controversy at all refective of reality, though? Isn't the idea that all humans move 30', or 6 squares, or have 6 movement points or whatever arbitrary, flawed and (in some sense) broken? It is
fair, in that it treats everyone as 'the same', but that is hardly the way life is. What about reaction time? or indecision? or the fact that a character can cover the same distance in a straight line as one who makes a 90 degree turn?
What if we look at the whole process as being representative of far too many variables to be worth tracking (was the character moving in that direction last turn? was he prone? what way was he facing? why can't anyone get in his way? etc. . . ). The same thing applies to distance: why is the 'range' of Point Blank Shot
exactly 30' or 6 squares for everyone? why can't it be 32' for some, and 27' for others? does it matter? Why does does someone .001 feet outside the area of effect of a fireball take absolutely no damage, while someone just a little closer gets toasted?
Lets look at the rules of the game as a formula for representing "the way things work in the real world" or "the laws of the universe".
If we wanted to, we could introduce a Reaction Roll, to see how far you get to move each round; we could give spells and abilities variable ranges and AoE; we could roll for initiative each round; we could do all these things and they would allow us to quantify more of those variables; they would give us the appearance of achieving a closer approximation of reality at the expense of time and effort.
The 1-1-1 rule makes a sacrifice in the other direction, it recognizes that there are so many possible random variables - why roll them? Under 1-1-1 movement rules, sometimes you can cover more or less distance than others, or shoot further, or be affected by something you were not as close too - in some ways
this is more reflective of reality than the 1-2-1 rule. Rather than die rolls, time, and calculations - it uses the dynamics of the game board.
If we were to truly look at situation fom the character's PoV, would they really notice? No - because they don't think in turns and concrete, delineated actions. They do:
"The Troll is awfully far away - I hope I can get there before he finds a hole in the Rogue's guard. . ."
They don't do:
"I can just make it to the Troll with a normal move, even though he's on the diagonal because we are using the 1-1-1 rule.
They do:
"Your supposed to be watching my back - that Troll could have killed me!"
They don't do:
"I'm glad we weren't using the 1-2-1 rule, that Troll would have clobbered my Rogue. . .
Life is variable. Combat is variable. Life goes on - and the laws of the universe remain unbroken.
