talking about 'authors intent' by 'none' a few comments ago, i don't
think it matters how the inventor of ultima (Robert Abbott) intended the
longleaper to move, at the time of creation, i think it matters more how
he thinks it should move right now.
an author can create a game, and all the pieces move 'as intended', but
that doesn't mean the game will play 'as intended' .. for 'some reason
or other' .. and i don't think that is a fault by the author, games with
unusual pieces probably have to be play tested for awhile, and not
everyone has the chance to do that. i don't see a problem 'adjusting' a
game to 'fine tune' it, at a later date.
as far as the authors of games that sprung from ultima, they too should
adjust the movement of the longleaper to play best for their game, seeing
some of these 'ultima' games turned out to be different, and really
their own game, inspired from ultima.
