We aim to build a "Steam-like experience for DRM-free games". One of the major sticking points of DRM games, and why platforms like Steam have done so well, is that they provide awesome features like worldwide play-together, social features, and useful overlays and tools. We aim to replicate this for any game.
Don't get us wrong, we don't think Steam or Valve is bad. They are unusually consumer-friendly, and provide a great service. They will always have a place, providing a marketplace for DRM games. Drop aims to be the alternative.
