Edna & Harvey: The Breakout - Anniversary Edition
PaterAlf: I wouldn't recommend these games for an 8-year-old. They contain some violence, deal with some pretty dark stuff and/or the humor is clearly directed at adults.
Nah, I'd say they are definitely aimed at all ages just like The Simpsons or Futurama. It's perfectly fine if children can not understand every joke or the social commentary embedded within as long as they can still have fun with it. They will appreciate their childhood classics even more once they grow older and begin to understand what they missed.
And I wouldn't consider these games violent. Unless of course you are over-sensitive to violence and want to ban even cartoon violence. But I do not consider cartoon violence to be comparable to actual violence. Otherwise we would have to start banning or censoring children classics like Tom and Jerry.
