Hydrophobia: Prophecy is the most mundane game I've played in a long time. The water physics are impressive, but not utilised in interesting ways. I was expecting more sophisticated physics puzzles based on manipulating water flow. At the very least, I wanted to feel like water was something to be afraid of.
When I first heard about the concept I imagined Hydrophobia would seem cold, dark and dangerous. Survival horror where you stay just one step ahead of being submerged or swept away. It's nothing like that, of course. It's mostly a game about shooting exploding barrels and scanning for invisible-ink graffiti. It's full of grey corridors, cult-crazed soldiers, and crystal clear water sloshing from room to room. The main character is an inhumanly strong swimmer, and water is a handy tool more than it's a hindrance. There is absolutely no sense of fear.
