When C&C came out I bought it, I tried it, it was not for me.
But for some reason the C&C crowd (not unlike the Savage World people) can't seem to accept that people might not like the game. That doesn't mean they hate the Troll guys, or that they just don't get it.
I probably would have given C&C a second chance if not for the fans who get so defensive and react to ever little slight (real and imagined) against C&C. As I said there are dozens and dozens of games out there and I look for whatever reason to spend my money elsewhere. People who talk about their favorite game do so in the hopes of influencing others. And you've successful done that with me. I've been influenced to not play the game.
The issue I had with C&C (and it's been a while since I looked at my books so forgive me if I get a few of the details wrong) was it tried too hard to be a retro, 1E style game that some changes were made just for the sake of changing. A great example were the saving throws. I seem to recall it going back to the archaic OD&D setup (Poison/Petrify/Paralysis, Rod/Staff/Wand, Death Magic, Breath Weapons, etc) when the Fort/Ref/Will model was in every regard easier to grasp, faster to apply, and generally better suited to a game that intended to be rules light than what they went with.
Ultimately, it's like the designers couldn't decide if they wanted to be a rules light 3e or an updated 1e and tried to do both to the detriment of the final product.
Well one of the advantages (dependent of course on ones own preferences) of the saving throws in CnC vs. the Fort/Ref/Will is that you don't have any real dump stats... it makes every stat matter at least somewhat because it is attached to a particular save.
Why? There are dozens and dozens RPGs out there few gamers can give each one a chance. Fantasy games seem to be the most numerous and with established games like the editions of D&D and Pathfinder that people enjoy gaming with each week why should they stop spend money on something else and devote time away from their campaign to it in the hopes they like it?

It sounds like a great system for old school feel and using your first edition adventures. The thing I most disliked about older editions of D&D is Vancian spellcasting. Treebore's addition of an at-will magical blast would help, but it sounds like you'd still have to memorize spells. I always hated knowing that you had the perfect spell for a situation, if only you had chosen to prepare it that morning.
Thanks for the thread, it's good to hear what people like about different systems.
I find that C&C tries to be too many things to too many people, and doesn't do any of those things well.
There are better takes on "rules-lighter" 3e. There are better takes on "revised AD&D."
Many find that it hits their "AD&D spot." It doesn't for me, at all. It scraps all the little fiddly bits that were AD&D to me and replaces it with the SIEGE system. Maybe it's a 1e-2e thing. It feels a lot like 2e to me, completely vanilla, which is simply not what I'm looking for in AD&D. If I need an in-print AD&D, OSRIC or Labyrinth Lord with the AEC are both better bets.
It's not particularly rules light. Maybe by comparison to 3e it is. But by comparison to pretty much anything else, it's not. If I want rules light, I'll play Basic D&D. If I want rules light with a unified mechanic, I think both Tunnels & Trolls and the new Dragon Age RPG are superior games.
Of the half-dozen or so C&C adventures I have, I have found them to be between average and horrendous in quality. The cartography, in particular, is quite poor with keys and scale often missing and multiple occasions where the description in the text fails to match the map. In one adventure, U3 Verdant Rage, they forgot to include a map. They made it available as a download, but still it shows the lack of concern they seem to have for what I consider to be the single most important aspect of an adventure.
Of the C&C products I own, I find the original "Nostalgia" boxed set that came out back in 2004 or so to be by far their best product. If I were to recommend a C&C product to anyone, that would be it. Also, Gabor "Melan" Lux has made at least three fine free C&C adventures that I'd recommend people track down.
