For role-playing game purposes - not for gambling or serious competition or encryption of your super-valuable secrets - there is a question of what sort of randomization is needed:
* Truly random outcomes: Doesn't hurt
* Psuedo-random outcomes: Good enough?
* Unpredictable but unequally distributed outcomes: As long as nobody can know what will happen, is that sufficient?
* Unknown outcomes: As long as the players can't predict the outcome, that's what counts. If the game manager can avoid bias somehow, why not have them pick the number? Even use family birthdays, old phone numbers, etc., like people do with passwords.
All devices will output unequal distributions for most realistic N, and especially for shorter series. Games are played mostly in shorter series. Does it matter if, over the long run, the device outputs a perfectly equal distribution?
