How old are these "kids"?
How many sessions are they going to play?


The big thing that immediately leaps out to me if you plan to have players ready in "45 minutes" is that it takes much longer to fill out a GURPS/DFRPG character than a D&D character (even if you know exactly what you are doing) simply because there is so much to write.

I think either giving the players pregens, or at least pre-genning some elements (eg, let them fill out the char sheet as they like, but have cultivated lists of spells for all the casters, or figuring out a way to have most of the "mandatory" fields filled out for the templates so that you can at least save them from writing out tennish skills, and 1~4 advantages per occupation)

You might also specifically ban buying up any attributes to start with because that is the biggest headache on the template, and without the relative skill levels on the template, it makes adjusting the skill levels if you DX+1 someone annoying at best for someone that has memorized all of the skills already, and a huge timesink at worse as they have to look up all the skills on a cross-reference table to see if that one gets a +1 or not.

Casting talents are a little better in that regard because spells have their own section on a worksheet so it's obvious that "all these things get a +1"
