This wouldn't to everyone's taste, but if you like hidden object type games or point and click adventures, then this game (as well as it's predecessor) gives it to you in a nice Victorian-era hand painted environments, as well as the objects you collect, combined with some clockwork/steam powered tech as well.

Obviously play the first game beforehand, but this sequel does what a sequel should and improves on the first game quite nicely. It's got all the goodness of the first, but it's a tad longer, the story is more compelling and the general interface and gadgets are much improved.
