GTA San Andreas vs. GTA IV

Up until now, I was a huge fan of the Grand Theft Auto series.
Now, with the release of GTA IV, I'm very dissapointed.
There's way too much "realism" in the game.
The car handling is rubish (braking is awful), the camera is very sluggish (can't corner at all), walking speed of Niko is not very gangsta like (try to escape thugs at that speed, you're long dead).
If I want realism, I just go outside and drive my car!
Also, the sheer size of the game, around 15 Gb, is just scary! How much cr*p can R* pack into a game?!
Watch a small comparison (more coming soon), now in all glorious YouTube HD quality.
