d4 said:everything? assume you are new to C&C and don't have many of the rules memorized, and you don't want to open the rulebook.
In my playtest, we were all new to C&C. I used statblocks like the one I listed, and did not have to open the rulebook once!

d4 said:if the wizard wants to attack with his dagger, what is his attack roll? how much damage does the dagger do?
Okay, I guess I should have added the 1d4 for dagger.
If there were any modifiers to her attack roll, they would have been listed.
d4 said:if he needs to make a Constitution save, what does he roll?
He needs an 18, or 12 if it his prime (the primes are indicated on the statblock). Since this is the core mechanic of the entire system, it hardly needs to be listed on the statblock (anymore than stating "roll d20 and add bonuses" needs to be listed on a d20 statblock).
d4 said:if someone wants to arm-wrestle him, what is his Strength score / modifier?
Her strength is average -- no modifier. Thus it is not listed. Only ability scores with modifiers are listed!
Simply put, if something is not listed, assume that the NPC's ability with the relevant ability is "average".
d4 said:how many spells per day can he cast?
Okay, missed that one (4/3 should have been listed).

d4 said:a 3.x stat block is longer, but can answer all of those questions without recourse to opening a book. i agree with the previous poster that the C&C stat block looks very implicit.
Wrong! (Well, mostly.) The stat block is explicit. You can ascertain everything you need to know by looking at that statblock without having to look up the rules.
Sure, it requires some knowledge of how the statblock is organized (e.g. that it only lists ability scores that have modifiers; average ability scores are not listed; what a "prime" is; the fact that all ability score checks require 18, except for primes that require 12; etc.).
But the same is true for a 3.x statblock (e.g. you have to know that "W" means "will save" etc.).
Having played both systems, and having used both kinds of statblocks, all I can say is that the short statblock I listed (maybe with a few corrections) conveys the same amount of game-relevant information as a 3.x statblock for the same NPC.
More generally, nit-picks about the statblock I gave aside, surely it is obvious that a rules lite system like C&C will have shorter statblocks than a rules heavy system like 3.x?
You might not want a rules lite system -- fair enough! But one point in favour of a rules lite system (whether C&C, Unisystem, or whatever), is that the statblocks will be very short!

And short statblocks means less prep time for DMs -- which is very important for me.
