Episodes is comprised of two very-different pieces of DLC: The Lost and the Damned has you commanding a biker gang in perhaps the grimmest piece of content in the entire GTA canon. The Ballad of Gay Tony stands in perhaps direct contrast to that, as it's clear that the missions contained within are a direct callback to the fun-and-fancy-free days of the series. Both have some issues (the club management aspect is pointless, for one) but are still definitely worth playing.
