I agree, although most engines murder sound footprints (quake 3 is even guilty of this) when in game. Mainly alot of treble and mids are muffeled which creates a much more empty effect.
I think counter-strike has a nice sound to most of it's guns, but if you ever open up the wavs they are completely over-amped, they litterally clip at every milisecond in the sound file. This is to make them loud and also gives them more of a robust sound, but at the sacrifice of warping the sample a bit.
In reference to price, yes 180 is pricey, but the cds have a collective of about 250-300 sounds that are royalty free, which is what you're really paying for other than just the sample quality.
The Lucas Arts collection I bought a few years ago cost 500 for 5 cds =)
