Dragon Age: Origins

Zevran's pretty easy to bed and you're probably aware of this if you've played Dragon Age: Origins. In fact, he doesn't hide his vast history of lovers or the methods he employs to find them. Driving the point home even further, the “Easy Lover” achievement is unlocked once you actually seal the deal. No one's complaining but you know what you're getting into early on when pursuing this dirty Rogue.
