I've had a lot of luck recently with World of Tanks and World of Warplanes. They're not RPG's, but they are MMO. Not much investment needed for a playing either.
I recently played Neverwinter. I can't recommend it though. The leveling up is very fast (Which isn't necessarily bad on it's own) and when you hit end game there is almost nothing to do. The free to play formula is extremely expensive addons ($20 for a bag) that frankly make it not worth your time.
Other than that, there are literally dozens of free to play MMO's out there right now. Costs nothing to try them, but the time to check them out. I enjoyed RIFT when I played, but stopped before the first expansion, so I have no clue what it is like now.
I have my girls watching all the TV shows and movies I watched as a kid. They're 8 and 10.
The Princess Bride
Star Trek TNG
I'm also having fun watching this generation's classics. (Pixar Movies, My Little Pony, Phineas and Ferb)
If you're having a hard time getting your kids (of any age) to watch the stuff you enjoyed as a kid I would suggest not telling them when it was made and watching it.
There's quite a bit of difference between human experimentation and entertainment.
STOP RIGHT THERE. I wasn't commenting on entertainment. I was commenting on exactly the portion of his post that I QUOTED. Nothing more, nothing less. If you can't see that, you should really have your vision checked out. While technically a Godwin's law effect, the step was from one reprehensible group having data that helps society to another reprehensible group with the same. You may not like it, but the comment was on target, even though it included the Nazi reference (because his hypothetical HAS happened in the past and to forget it is a disservice).
If Al Qaeda came up with a cure for cancer, would we as a society start using it, or reject it as poisoned fruit?
Just as we accepted the medical knowledge unlocked by the nazi's during WWII http://www.jlaw.com/Articles/NaziMedEx.html we would use the cure for cancer. The foundation of treatment for hypothermia was all determined through the torture and murder of jews by the NAZI's, and yet we use that information to save lives even today.
I mean what I said. Acceleration is a different measurement than speed.
