Actually, you've mentioned exactly why I believe "minimizing prep time" is so problematic. To achieve it, you often have to change the way the game is
played.
So far, the two mainstream implementations that attempt to minimize play time have resulted in the following:
a) D&D 4E - derided as a very bad system as it severely limits player options, and despite its restrictiveness it's still unbalanced.
b) Warhammer 3rd Edition - derided as a really, really weird system that can't decide whether it's a boardgame or an RPG.
"Indie" titles have also tried to make prep time shorter, most notably
Mouseguard which many see as an improvement over the overly complex Burning Wheel system. However, Mouseguard also plays very differently from D&D - it very much encourages a Magic Tea Party style of play.
And that's really my point. If you go beyond the existing tools (i.e. Pregens), you're gonna end up having a very different kind of game instead of the traditional RPG experience.
Shifting tools to an online database help, but only a little. The main advantage of an online database is that you can
sort monsters and other data the way you want. Sort them by level, by exp, by name, by type, etc, and it will be done instantly. Boardgame/RPG hybrids try to simulate this by using cards, but it's not as fast as sorting via computer.
However, in order to speed up the actual
selection of monsters, you need to do 2 things:
a) Have a really short list of monsters per category. If your choices for a level 1 challenge boil down to "Orcs or Kobolds", selection becomes REAL easy.
b) Have a really short description for each monster. Which is actually 4E's problem - the monsters are just blobs of HP with one or two unique gimmicks. Meaning that making them exist in any situation outside of combat is very difficult.
In other words, I don't think you can transfer 4E "minimize prep time" tools to other games without
also bringing in the gameplay elements that made it suck.
Now, someday, somebody might pleasantly surprise me by creating a D&D-style RPG that has minimal prep time, without having 4E's retardness, and without becoming a Magic Tea Party (I wouldn't mind Warhammer FRPG style bits, as long as we don't end up with thousands of pieces).
But at the present time, I just can't see how you can do it.
(Also, I can explain precisely why it takes only 30 minutes to teach Battlestar Galactica, while it takes hours to create characters, and how applying techniques from the former is impractical in an RPG. But that's another long rant
)
