thirtysmooth said:The G is a knockback from TSA's sister site, TA. It's short for 'Gamerscore'. As Steam achievements don't have a base value like the Xbox platform. TSA applies a base value of 10 per achievement (except for achievements that are classed as spam).
In your case, you've earned 2,371 achievements. Times this by 10 and you have your base score (or G) which equals 23,710.
I always thought it was some kind of conversion + defaulting system, where it drew points from the xbox achievement list (if the game has one) and then applied that, and just used the 10 base value for games that didn't have an xbox port.
Not sure how I didn't notice it didn't work that way until just now lol.
