6. Mass Effect

Country that banned it: Singapore

If you picked your character and game actions carefully, the latter stages of Mass Effect could give you an eyeball at a steamy lesbian alien sex romp. The alien in question is a blue-skinned Asari scientist with long skin flaps instead of hair.

Exciting though alien lesbian sex sounds, it isn't quite as titillating when you realise that all you get to see is a flash of xenomorphic buttock and it takes you a good ten hours of porn-free play to get there. Not to mention careful attention to dialogue options. Singapore's censors were eventually satisfied with an upgrade to an 18 rating after a public outcry.
