Personally, I've worked on several of the branches of the Diku

codebase, and most of them used a similar system. Quite possibly

because of the close affiliation.

Sure, using the same equation the outcome may be different, but

there's always the (much better imho) option of using different

equations and tweaking the input values.

While I agree with these sentiments, I think that this can be

handled with the random number equation. I've seen equations that

use the number of dice to control the distribution. It may not be

100% correct, but it's close enough.

Granted it's a minor optimization, and unlikely to affect game

performance, but you also have to consider that a slightly more

complex algorithm is often cheaper than repeatedly applying a

simpler one.

Honestly, the linear distribution is fine with me because frankly,

it simplifies system design.

If each value has the same chance of appearing, it's a simple matter

to calculate the chance of a range being chosen. I can state that I

want .01% of dice rolls to be critical hits with 1.5% to be critical

misses.

I think few players care about the random number distribution

(assuming it's not hindering their gameplay). I've personally never

heard of a mud player mapping out the dice distribution.

Considering that game developers need to take it into account in

order to make good decisions, I'd rather KISS.
