Debriefing - hell, I'd never thought of it that way

I tend to discuss gaming sessions that we'd just gone through (I'm the DM/Gm/God/Whatever) in a purely informal manner - since I have a LOT of gaming virgins at the table (Maybe half haven't got to 2nd base yet) they and I have found it invaluable.
Sure, there are some uselessly funny situations when the player is trying to butt their way through a problem ("He's not talking...and I have a shock glove built into my cyberarm...hey, wait, can I torture people?"*) and through more luck then anything else succeed... But the majority of them listen to the shop-talk because it IS so useful.
Sure, you may have a rather ripped character with a CHA of 8, but why does the fugly Troll get the sweeter cut of the deals? The ins and outs of background skills, character development, where to get good in-game porn (I am writing these runs up, half the time I don’t believe how well these guys adapt) or what it actually means to initiate – unless they can make the connection, half the time they’re just along for the ride until they hit something they can use.
Decreasing the learning curve is good for grabbing their attention – you don’t dumb down the game though, just make it easier.

I.e.: “So, you have a character with connected Lev 2, and he’s an Arms Dealer. Sure, you could get you hands on that Assault Cannon dirt cheap, but he’s got to source it, and the market right now is not really good for heavy stuff like that, you know, all of that random gunfire does makes the public nervous, and Lonestar look for the source of that EXEX ammo. ..”
[Big group nod]
“Other than that, he’s got a couple of boxes of Neurostun darts and Grenades that are reaching their use-by, interested in a bulk discount?”
[Questions raised:]
“Yeah, the guns were a lot excessive…Neurostun? What is it? How useful is it?”
[Answers (Varied)]
“Well, if you’d tossed a couple of these in that last building’s aircon system, most of those guards would have been all sleepy rather than hopped up on those nasty combat drugs.”
[Team:]
“Woo. Ok, hey, can I get those combat drugs too?”
[GM:]
“Sure…this is what they do…”
[Show benefits]
[Team]
“Waaaiiiiiiii! No wonder they kicked our sorry lame asses! How much? Gimme!”
[GM] (Patiently)
“I’m still going…this is what they ALSO do…”
[Show the addiction effects]
[Group recoil]
“Arrgh! Holy crap, get it away from me!” Etc.
Looking at what I’ve written, it’s not so much a debrief – although they do ask some pointed questions as to where all those NPC’s came from – as a discussion on how the game played, and how well they did. A lot of that is how much they learnt and how much they put what they know into use.
So debrief, but leave some secrets. Pay no attention to the elf behind the curtain.
* So you know, in my games the answer is "Yes" - but whatever they do to people, I will allow the opposition to do to them.

This has come to really reinforce the learning curve when it comes to the indiscriminate use of heavy weapons. Although the first guy with a tricked-out Machine-gun is in awe of what it can do.
