This game has an allure because of its revolutionary concept, but not all is delivered. To make it short:
THE GOOD:
-incredible graphics, with or without a card
-free atmosphere that just begs to be explored
-somewhat of a branching storyline and some choices along the way
-huge, seemless city areas
-great concepts - many inhabitable characters and NEARLY endless possibilities
THE BAD:
-the four different 'modes' (adventure, shooting, fighting and swimming) are kind of annoying
-the objects (books especially) are somewhat repetitive and limiting
-all the people in the street... do they all look EXACTLY the same or am I seeing double - triple - quad... AHHHHHHHH!
-I personally don't like the concept that you are REALLY sitting there playing a computer game which is controlling bodies in another demon-infested parallel universe... I'd rather put myself in the position of the character than just be myself sitting on my butt
-for the life of me, I can't drive those blasted cars
-some of the puzzles are very hard and in some, the solution doesn't really make sense. I had to buy the PRIMA strategy guide, which, in a bind, I recommend.
