That's incorrect. Metacritic rated Mafia III at "68." The average user rating was 5/10. Other games sites have an average user score of a "6."

Again, the game suffered from issues with crashes and glitches. It's not a bad game, but it's forgettable. The strongest point of the game is the dialogue and story line. Everything else appears to fall short with the missions be repetitive. The controls feel unrefined.
As of now, you can find the game new for $25.00. I wouldn't pay over that for it.
Edit: Continued playing tonight. More unnecessary glitches with cars floating and icons popping up in the wrong places. These are the types of glitches that frustrate gamers and take away from the experience of the game.
