Games For People Who Actually Want to Solve a Mystery
There's no hand holding in ND games. They're tough to solve even in the easier modes with a few hints available. (versis the hard mode with no hints)
I'm a long time player of mostly Adventure, RP and HO Games, but the only real games that I totally get immersed in are the ND ones. And I'm so sad when they come to an end.
Yes they seem a bit "out of date" video-wise, and the heroine is an older teen/young adult, so some of the dialog between ND and her friends may seem too young to many players. But don't let that keep you from enjoying the great game play with good solid storylines and fascinating locales.
And there's always one or more bonus games within each game, that you can play to your heart's content.
As old as I am, I also enjoy the information I learn with each game, like the Icelandic language, and the folding symbols for Origami.
It's obvious that a lot of thought is put into these games.
