Game Room

This achievement requires paid content.

To earn this achievement, you must unlock 48 medals cumulatively in Game Room. Each medal is only counted once. If you unlock a bronze medal, and then unlock the silver medal of the same type in the same game, that is still only one medal.

At a minimum, you will need to buy 16 games to unlock this. This is assuming you only buy games with Survivalist and Point Buster medals.

There are three medal varieties:
Point Buster : These medals are awarded when you reach certain score targets.
Survivalist : These medals are awarded for surviving a set amount of time in a single play.
Time Spender : These medals are awarded for cumulative game play.

Every game has a Time Spender medal. Time Spender medals count the time spent playing the game across any mode, including demos. Once you have played the required amount of time, you must either own the game (or be playing it on a box that has license to that game) or buy a paid session in order to actually unlock the mdeal.

Most games also have a Point Buster and Survivalist medal. These medals can only be earned in ranked play, and in games that you either own, are purchasing sessions with using the 40 MS point option, or on games that your console is licensed to (i.e. Someone else bought that game on your console). These medals can NOT be earned in demo play, classic play, or if you are using tokens to play a friend's machine.

A chart of which games have which medals available, and the goals that must be met to get those medals is posted here:

Here is a list of all the games that I used to finish the game really easily. It is full of alot of rentals that you can either turbo one of the unused buttons or hit start to continue the time.
If the timer stops counting be assured that it will still count for the gold. There is a timer at the top left of the screen that will tell you how long you have been playing for. You can verify how long each game will take here: http://www.tinyurl.com/GameRoomMedalChart
