21. Dragon Age: Origins
Bioware is one developer that has certainly never shied away from featuring sex in its games. And Dragon Age is one of them. It certainly was a jolly good RPG back in 2009, with a great story, gameplay and a cast of characters more colourful than a Christmas tree. Amongst those characters was Morrigan, a cynical witch with an attitude problem and a potential love interest for the player character.
And it was possible to get intimate with her in a tent. That is if you followed the right conversation path and had the patience to put up with her wisecracks… Your reward would be a mostly innocuous sex scene and Morrigan would dismiss you afterwards. Oh dear.
