Ok, Jack Orlando is a good old-school adventure game. The setting, plot and characters are just like in the old "noir films", so if you like this kind of movies - as I do - you will probably love the game. However, the game fails in may other aspects: the main character is not very likeable, the voice acting is terrible, some puzzles are irrational, you can die (that's something I don't like in adventure games) and you can pick up too many useless objects you don't have to use (and believe me, is hard to tell which one is useless and which one is not).
So, in a nutshell the game is good, but doesn't play in the same league as Lucas or Revolution.
