I'm a bit disappointed, the sensationalized subject of this thread alone sounds more like something I'd expect of the Inquirer, not DemoCoder.
I think I already explained in a thread in the Game Talk Forum how the BPjS (the institution resonsible for indexing C&C:G) works. First of all, an indexed product is not fully censored like some people here seem to think, it primarily means access is restricted to adults and no advertising is allowed. Stores are allowed to keep these produts on stock and sell them to everybody over the age of 18 though. To summarize my other post, the 4 main criteria for a "script" to get indexed are pornography, excessive violence/gore, Nazi ideology/symbolism and belittlement/glorification of war. Considering Germany's recent history I think the last 2 points are understandable.
The (unfortunate) reason the BPjS is so actively involved in indexing games compared to their in comparison minimal engagement in other contemporary media is, that the independent age rating institution for entertainment software (USK, which rated C&C:G as 16+), unlike its counterpart for movies (FSK), is not legally binding. This basically means there is no fully working or binding age rating system in Germany for entertainment software. To counter this the BPjS is sometimes taking things too far, which is why I hope the USK (which IMHO has a much more competent board of advisors and experts when it comes to games) will in a not too distant day in the future be similarly responsible for rating games, as the FKS is for movies (which is basically 100% the same as the US Voluntary Movie Rating System except for different rating criteria that are often due to small cultural differences, e.g. more sex but less violence is in general tolerated here). This would take almost all of the influence over games out off the hands of the sometimes over-sensitive BPjS (e.g. according to law the BPjS can only consider indexing a movie if it has either not been rated at all or rated 18+ by the FSK).
It might interest some here that a pretty large group of people is currently fighting this and other BPjS indexing decisions in court and things look good AFAIK.
