@Bluepixie: For one game alone? I'm not quite sure to be honest, but if you can get a Wii cheap enough, then maybe. For as much as I love those games, you can never legislate for another's enjoyment.
As for Dreamfall, I had pretty much the same experience; it has this very sombre tone which I loved and it's such a shame we've not had any follow up to what was a very inconclusive stopping point (it doesn't really "end" per se). Oh, and thanks :)
