I have been playing Dreamfall recently. Great game, except the fact that the player is force to go from A to B and then back to A very, very often. It seams to be mostly pointless – except making the game longer in an unfortunate way.
Then, there is the issue of the game trying to hard to tell the player when choices matter, with flashing HUD and what not. Most of the time the player does not have a say or a choice, and that becomes so much more obvious.
It is still a good game and definitely worthwhile.
