Hi, timing can be really funny at times, I've recently done 
some cleaning and reogranising of my room, which lead to perusing a few 
old copies of Dragon Magazine.  One interesting article was looking at 
the concept of wishes.  This was done in AD&D terms, but after seeing 
some of the wish related story's that have been posted latley, I 
thought that the varried types of wishes might provoke some ideas or at 
least a chuckle from some of you.  In summery here they are.

Types of wishes
Wish of Omnipotence:  or wish of Ultrapotence, this is the wish that 
can produce solid gold castles from thin air, reshape the continents, 
or change great armies into lemings.  Basically it can conceivably do 
anything, though circumstances somehow always prevent it from being 
used at full capacity.
Wish of Contrivance:  To draw an example from Mage, this is the static 
wish.  For instance, if Ranma wished to be cured of his curse, the 
other wishes would more or less act to correct the problem, this wish 
would cause Ranma to sudenly get a barrel of Nanichuan water from 
somewhere.
Wish of Expiration:  This is a wish that only lasts a certain period of 
time.  You could consider Cinderella an example of this sort of wish, 
being granted everything to go to the ball but with them fading at 
midnight.
Wish of Limitations: This is like a wish of Expiration, except instead 
of only lasting a certain period of time, it will only work within a 
certain location.
Wish of Malevolence:  This is the Monkey's paw wish.  Basically it 
fulfills the letter of the request, but pumps as much evil and 
suffering into the details as possible.
Wish of Benevolence:  This is the opposite of the Wish of Malevolence, 
whatever evil or selfish elements the wish had are eliminated or 
changed.  IE, if Happi wished he were kneck high in panties, he might 
sudenly find himself helping launder the clothing at a childrens 
boarding school.
Wish of Contrariness:  This wish grants the opposite of what was wished 
for.
Half-Wish:  This does half of what is wished for.  If Nabiki wished for 
fifty pounds of gold, she might get 25 pounds, or a fifty pound weight, 
or she might suddenly gain fifty pounds.
Wish of Overkill:  This is a wish that does what asked of it, then it 
does more.  If Ryouga wished he could tell Akane his feelings, he might 
find himself confiding his feelings with everyone.  Or if Shampoo 
wished Ranma loved her, it could affect Ranma, Ryouga, Kuno, and any 
number of others
Wish of Vagueness:  This wish gives roughly what was asked for, but the 
details are a little off.  A wish for a magic sword could produce a 
magic axe, Ryouga wishing that Akane loved him could cause Nabiki to 
suddenly fall for him.
Wish of Misinterpretation:  This wish never gives anything similar to 
what was asked.  If Gosenkugi wished for incredible strength, he might 
develope incredibly strong bad breath, if Shampoo wished Ranma loved 
her, she'd sudenly be pursued by a lovesick wild horse, if Nabiki 
wished for untold riches, she might get untold roaches instead.
Wish of Unspoken Desire:  This is a wish that warps the meaning so that 
it would grant whatever hiden desire lurked in the Wisher's heart at 
the time the wish was made.
Wish of Least Resistance:  This is a wish that always grants the 
request in whatever way would change reality the least.  If Kuno wished 
for a magic sword, the nearest magic sword matching thoses 
specifications would be teleported to him, never mind that it's owner 
would be furious about what happened.  And of course if Ryouga wished 
Akane loved him, he'd switch bodies with Ranma.
Wish of Credit:  This is basically a wish that has a limited cash 
value, ie if you wished for money, it would only be able to grant that 
limited amount, if you wished up an earthquake, the total damage would 
be exactly that amount etc.
