@Klumpen: I agree with some of your complains about Dreamfall, I felt the same about the rail->cutscene->rail->cutscene with far too simple puzzles here and there, but the more time passes since I played it, the more this fades to be replaced with the impact the story/themes had on me. But this was probably different for me, since I did enjoy the characters, especially Zoé.
For the voice-overs, I'm used to always switch games languages to English whenever I can, because French translations and voice-overs are pretty much always terrible, with a few exceptions here and there (most French games have good French voice-overs, male Shepard was far better in French than in English, Ultima IX voices were ok, while I read they were terrible in English, etc.). While Zoe's voice didn't have the charm of April's, I didn't have any problem with the English voice-overs.
