Winner: Mass Effect
Microsoft | 360

Even since we saw Captain Kirk get TV-safe freaky with that green-skinned alien chick who was summarily blown up, the dream of getting primal with a space-babe has loomed large for all of geek-kind. However, it takes a special kind of guts to make that wish come true, and developer BioWare went above and beyond the call to deliver the goods in Mass Effect.

This galaxy-sized space opera boasts not one, but two possible sex scenes between the player and blue-hued female aliens. Though, to be honest, that first one wasn't very graphic so officially, it may just be one and a half sex scenes. That's okay. Our imaginations filled in the gaps to make it two.

The final triumph is that your character can be either male or female - so it's not only alien sex, it's alien lesbian sex. We can't explain why it's hot - one of these ladies could give dork lessons to Thelma from Scooby Doo, and even the sultry one has blue skin and slicked-back squid tentacles where her hair should be - but we can't deny it either. Talk about going where no man (or woman) has gone before...
