Everything has badges and achievements now. Every Steam game comes with achievements, Xbox and PSN have their trophies, there's groups dedicated to platinuming a game (100% achievements), etc. A large part of gaming today is about showing off to everyone just what you've accomplished. Initials on a high score board don't cut it anymore, people want something they can post to socials, etc.
