Your second point is the important one for most games I think. Global leaderboards on a popular game are meaningless for the vast majority of players (do you care that you are in position 324,675?) and almost all of the implementations I&#x27;ve seen have been hacked. As this thread has discussed it&#x27;s hard to protect false data from getting in the leaderboard.<p>Limiting leaderboards to friends both gives relevant context for fun competition and mostly eliminates the cheating problem by making it a social issue. I know my friends wouldn&#x27;t be happy if we were all competing on a game and I cheated.
