Secret World & Some Analog Gaming

I'm still playing Neverwinter on a daily basis, but my level 42 devout cleric has hit a spot where I cannot proceed solo.  I have taken my great weapon fighter up to level 22 or so, and am having fun there, but figured I'd change gears a little bit and give the Secret World another go.  I'm having a fairly good time with it.  I understand the criticism is that it doesn't have much content, but I'm not in a position to judge that just yet.  I guess the thing that I'm enjoying most about it is that the questing feels more ogranic.  I can be on a quest, and see a side mission and elect to take that.   There's no real leveling in the game, so all you have to go on is "normal" "hard" "very hard".  I have taken my share of hard adventures and some are grueling while others aren't too bad.  The other thing I like is how the game challenges you to use outside sources of knowledge to solve a puzzle.  Being asked to translate latin, look up bible verses, hit wikipedia is really an interesting way to incorporate every day surfing and "googling" into a metagame.  Now, being realistic, that lasted about an hour and then I was all "secret world - digging deeper walkthrough", but still, it's nice to know that a robust tapestry of puzzle solving exists if you're willing to invest the time.  While I don't expect to go too heavy into TSW, it's coming on strong as a good 2nd or 3rd go-to game.  

Marvel Heroes, on the other hand, is facing a fall out of the top 5 rotation of games.

Words cannot describe how much I am digging Elder Sign as a tabletop game.  The IOS version, Elder Sign: Omens is fun enough, but it cheats like hell.  The other night, my iPad was dead, so I decided to set up the tabletop version of the game and play solo.

I've been getting more into tabletop gaming as a way of involving the whole family in an activity.  I can't stand when my girlfriend sits in front of the tv for an evening, or the boys are playing xbox or wow - and I know - glass houses and all, I'm usually on the PC or Xbox or PS3 for a good hour+ per day.  (by the way, I'm not really digging Last of Us). Anyway, I see a need to get us more connected - so I've been going deep into tabletop gaming.  King of Tokyo was well received, though I found it a bit stretched out.  Forbidden Island is way too unforgiving for anything short of a hardcore group.  Fluxx and it's variants are a hit, but I find it too simplistic.  Dixit Journey was also well received, but with the kids, it's far too easy to sort out what they're doing.

With all that said - I've decided to expose my girlfriend's kids (what do you call a lady you've lived with for 3 years, dated for 4.5?  Girlfriend seems so 'temporary') to D&D.  The 4ed red box should be at my doorstep when I get home tonight, and I figure I'll have them roll some characters and then I'll take them through a small adventure.  Myself, I haven't played D&D for over 25 years, and even then, I wasn't hardcore.  I figure we'll all be learning as we go.  They had a good time with Castle Ravenloft (we did simplify quite a bit), and I'm hoping the pen & paper will stir a spree of imagination in them (and me too, the workaday world sure can limit creativitiy).  Any advice to a noob DM with noob adventurers to shepherd through some dungeon crawls?
