Problem with rating
Is that bbfc don't just have to play the game, they have to play every possible ending and plot split from the main game.
Take C&C for example in 1995, it says B**tard, on the last level for the GDI. But unless you play that bit you don't get it.
Also take in Clive barkers undying, if you type in the cheat codes (easily given as they also let you fly, have unlimited ammo etc) that lets you walk through sections previously out of bounds or locked down, then you get to see one of the maids of the house in her undies because the devlopers left them in there for a laugh.
So are the BBFC going to have to check everything, including all easter eggs. Or are they just going to test the main game.
Also they would have to listen to every single sound bite recorded for the game.
Warcraft 2 expansion, click on a character a few times and they talk to you in a funny way, one female elf talks about a g string not bow string and that you are touching her in a way you don't touch the others. :)
Now consider far cry or mass effect (which also has an achievement that includes sex with aliens) it takes about 4 days of playing to work through that, never mind all the possible conversations you can have if you play male of female characters. You'd need a copy of the script instead of playing it.
So what are the BBFC going to do, rate on what they get to in a time limit, or what the developers tell them is there.
I also would bet the BBFC are not hard core game players.
It won't work, never mind the fact parents buy it anyway.
mines the one with "sad old gamer" on the back.
