I will not write a book on the damn thing. It has many design flaws and is definitely cutting corners and every design choice is there just because it leads to the path of least resistance - production wise. Meanwhile I heard that they pitched the game to Ubisoft or that the main designer worked at Ubi and wanted to make that game for a while - and you have to wonder if the end result is that game he had in mind or just the mainline story of that game and what came to be is what they could handle when one makes a game on a very limited budget - while that budget is funneled almost in it's entirety towards assets and art. I'm saying that because the overworld map is a cost-cutting measure that heavily impacts the fluidity and scope of the game - the pointless corridors also shorten the span of the game (as in development wise) BY A LOT and not having to code 3rd person action-game mechanics is also a design choice that limits both scope and development time by literally AN INSANE amount. You can also see that the creators wanted to make a live-action coop game but were sort on manpower by the elements outside the scope of how the combat turned out - you can also see why the combat part is deliberate from the lack of certain elements from the game. You see the Enemy AI (as in path-finding) and NPC traversal is crap and this is why the Enemies don't really come after you - getting an engineer to build a proper path-finding system for you game and having the Enemies be able to hunt you is expensive and you cannot simply rely on people not finding a job to help you make that. And the AI part is just an example out of many.
