This game still has better graphics than more recent games.

The player has more liberty in the first game. It's not really an open world, because you have to go from a point to another, but you can choose your path. You can follow the road, you can go through the vegetation, you can swim underwater. You can walk, swim or use a vehicle. You can strike frontaly, or act like a modern ninja in a nanosuit...

This game can be played as a shooter as well an infiltration game... This game has a great replay value !
