Gamers Achievements vs MetaGamerScore

Gamers Achievements has no write-up on Specifiction yet; its figures are above.

MetaGamerScore is a free web service that combines gaming achievements from multiple platforms into a persistent metascore. It automatically values achievements by rarity, while game and achievement values are adjusted for popularity and rarity. The service says it supports 30 platforms and game services and retains history from 8 retired integrations. Its listed services include Steam, PlayStation Network, Xbox Live, GOG, RetroAchievements, and Roblox. Users can compare games and achievements with friends, compete in global, country, yearly, crew, completist, and world-first rankings, form crews, challenge friends, and share achievement guides. It requires no client installation. The FAQ says the service does not ask for gaming passwords and collects only data available without them. When possible, it preserves linked accounts and achievement history after an integration shuts down, a practice it says dates to its 2011 launch. The service is not open source. It is free to use, with optional monthly Patreon pledges for perks such as more frequent achievement scans, ad removal, custom profile and crew URLs, and extra crew slots. Patron perks are added manually after a pledge goes through.
