I think it would be neccasery to create a internet, movie, video game, database. I mean i know there already is a igcd but it should be runned by the imcdb ("people"/company).
What exactly do you mean?
IMDB already lists a number of video games. But
http://www.mobygames.com/ is a more extensive video game database (IMDB isn't really suited to cataloguing games).
Or are you saying there should be a car-in-games site that is run by IMCDB? IGCD has the same basic format of this site and it's run by two IMCDB members. IGCD is pretty much a video games version of IMCDB. So this idea is very redundant
By the way, IMCDB is not any kind of "company", it's a non-profit website that people contribute to in their spare time and antp is the person who handles the real maintanance of the site (programming, web hosting, fixing problems etc.) And the only money involved is the subscription fee antp pays to the hosting company.
