new Assassin's Creed - does anyone know why it is rated 18?

[fourkids]

Assassin's Creed isn't my cup of tea at all, but DSS has it and DH is happy with it, so who am I to promote Animal Crossing instead!!!

We are just looking at Christmas presents and have noted that the new Assassin's Creed has jumped from 15 to 18. Historically this would make it a complete no-no, but before making a decision, I just wondered if anyone or their DC or DH has played it and can compare it to older versions, ie knows why the rating has been increased to 18?

many thanks...

Ignore this! I've just decided it was a silly place to put it...just because I think that computer games are for kids, doesn't mean that that's a fact. I'll rewrite it in chat...
