CZ 75 & Gun Names in Video Games

[Chaosut27]

This is actually really two questions put into one thread, which i hope people don't mind. It's just that i've already made another thread so i didn't want to be taking up the whole forum lol. But anyway, these questions might seem a bit silly or incompetent, so try to bear with me.

1) One thing that i've noticed is that the CZ 75 doesn't seem to be used in that many films or video games. I've always thought of it as a pretty popular and competent handgun. But comparing to say the Beretta 92 series, H&K USP, Glock pistols etc the list of media that the CZ 75 in is far mor sparse. Does anyone know why this is.

2) As you probably know, gun names in video games are often different to the real life counterparts. They seem to be often made to only slightly resemble the name of the original. Eg. in Hitman - Blood Money the Tarus Raging Bull is called 'Bull .480'. In STALKER - Shadow of Chernobyl the Franchi SPAS-12 appears as the SPSA14. But anyway, you get the idea. This kinda annoys me just because i really like to read the real guns names. So is it because then the video game designers would have to pay to the respective companies? How about if they for example called the Heckler & Koch MP5 in a game the MP5, then the company name is not being used (though the model designation still is i suppose). I think in Call of Duty 4 they called it just the 'MP5'. Or is it some other reason that they change the names?

Anyways, thanks for your time .
