Why do some PS3 games require HDD installs?
MTV have found out that some Blu-ray games require installs to the hard drive because Blu-ray drives can only read at one speed.
"When this is combined with the extremely large size of Blu-ray discs, and simply dumping existing DVD data onto a Blu-ray disc will inevitably result in longer load times."
To quote: The issue arises from differences in the reading techniques of DVD and Blu-ray. By nature, the outer and inner parts of a disc move at different speeds while a disc is spinning, regardless of format (CD, DVD, Blu-ray, HD-DVD, etc.).
While DVD drives can read data at those differing speeds, Blu-ray reads at one speed. Combine that with the extremely large size of Blu-ray discs, and simply dumping existing DVD data onto a Blu-ray disc will inevitably result in longer load times.
Installations are a way around this issue.
When a publisher asks you to install a game on PS3, it's because they're moving some of the disc data to an area of your console that has much faster read access: the hard drive. You get vastly reduced loading times, but have to sit through an installation.

but BluRay reads faster as well don't it? i mean a bluray reading at the spead of '1x' reads at 12megabits (or megabytes dunno).. compared to a few megs for DVD.

15mb out of tons of megas the disc can contain... so the reading ratio is kinda 1:1 compared to DVD.

i don't mind the installation of games at all. On ps3 it reduces the loading time vastly as seen on dynasty warriors where as compared to xbox360's its hardly noticeable.

But why is it that a game like Unreal Tournament 3 has an install option but does not require it to be mandatory?

That would actually be 36Mbps. so its 3x the speed of a 1x DVD. BD-ROM specification states Movies at 54Mbps and Data transfers at 36Mbps, So would guess it reads 2x on video/audio and 1x on games.

i dont mind the installation, but the wait time in devil may cry 4 is too much.
