At first I totally agreed with Cynical Cat, but now I think I understand both sides of the discussion.
Yes, the system is good, but anytime you have humans wrestling ogres into submission, you have to step back and take a look at the statistics. GM improvisation and control are always good, and necessary at times, but I think that many cases may call for too much of a stretch. Maybe there should be a change in the difficulty factor, or it could just be ruled as impossible or automatic (in either case, no roll). (The party in the ogre situation would still have a good laugh, but for different reasons.)
Not that the whole rule system needs to be revamped, but maybe there should be some clearer, different modifier somewhere, specifically for some of these issues.
Overall, I like what I've seen so far of the 3rd edition rules. I'm not sure how it will play, but I'm optimistic.
"Fun is more important than flawless."
The bigest problem I can see with the new system is there will in generally always be a soft cap (or sweet point) on all results happens to be, below or above that point will give diminished returns.
Add to that the luck/unluck factor of the challenge dice and It may very well cause stranger outcomes than the results you get in 2nd ed. Take the orge wrestling, it is quite feasable for the challenge dice to not result in any increase in difficulity because no faces come up countering the success/es (while the ogre produces no successes of their own), so a 10 pound weakling could concieviably win the wrestling match.
So this would be one problem (and those of a similare nature) I can't honestly see being actually 'fixed'.
And whith multiple dice it will be much harder to determine for the GM the relative difficulity (though im sure practice with the system will compensate this to some level).
