Long Time No SeeG 100

You have to play one of the mini games and stay off for a while. The smallest time frame to remain away from the game is unclear. Some folks tend to stay off for a little as one week to as long as over a year to get this. A quick way of doing so is to set your PC to a year back, play a mini game, close the game entirely, set PC to correct time, reopen game and play one of the mini games. The achievement should unlock after this.
