These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Doing It for the Art - The "making of" video shows how painstaking they were about accuracy, the quality of the live art nouveau animation, the intricate-yet-flexible storyline, and the depth of characterization right down to individual reactions to meeting the protagonist in the corridor.
Good Bad Bugs: All of the fight scenes in the game can be bypassed by repeatedly pausing the game, going to the menu, and unpausing. Doing this enough times skips the fight as if you've already won it, except for the last one, where you have to take one more action to avoid being killed.
Stillborn Franchise: The Last Express hints at an awesome sequel in which both the significance of Cath's ring and the reason behind his all-consuming drive to get to Jerusalem will be revealed. The suggestion that the 13th tribe of Israel may be involved somehow makes it all the more tantalizing. These would all be spoiler tagged but there will never be a sequel, so we will never know what happened.
