GastonArg: a lot of people hated the whispered world because of the voice of the main character, I think it's just different and you need time to get used to it, the plot was very good and sad, I love sad stories specially in adventure games.
Most of the new adventure games ends up well, the hero prevails the bad guy die or it's defeated etc etc, daedalic made games were there are not heroes, you are just a person who cant solve and fix everything and in the end you do what you can, like in memoria or eyes of satinav,
Or games with dark and very crude humor like deponia or edna and harvey, you just dont see this kind of games anywhere...
You're spot on. One of my personal favorite poets, a Portuguese crazy lady called Adília Lopes, said once that people relate better to sad stories because we feel our own pain more intensely than our joy or happiness. Daedalic are masters of crafting and delivering sad, engrossing tales in their games.
You mentioned Chains of Satinav and Memoria, which are two fine examples of what we're talking about. I don't know much about Das Schwarze Auge/The Dark Eye universe, but I think it's safe to assume that, like its US counterpart, Dungeons & Dragons, there would have been "better", more heroic and brave characters in that franchise to choose from, rather than a simple lowly bird catcher. And yet Geron was the character Daedalic chose for their point and click adventure series set in The Dark Eye world. And I'm glad they did. He's "one of us", he's easy to relate with, has human flaws and qualities, has doubts and passions. And though I was expecting that bittersweet ending to Chains of Satinav, it didn't make it less sad and touching. Really, really well done by the awesome storytellers at Daedalic.
[EDIT] As for Sadwick's voice actor... well, it wasn't my favorite thing about the game, far from it, but it wasn't as bad as people make it out to be. In this day and age people just enjoy nitpicking, I guess...
