MetaGamerScore vs TrueAchievements

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.

TrueAchievements is a web-based Xbox community for tracking achievements and gaming accomplishments, alongside news, reviews, features, and achievement help. A free account provides game and achievement tracking, while members can organize game collections, follow progress across game series, and set scoring and completion goals. Tracking requires the Xbox profile's game and app history to be visible to everyone. The site hosts more than 3,000 community-created walkthroughs and achievement guides, with bookmarks that persist across devices. Its free Xbox One app includes a gamer homepage, game lists, achievement solutions, gaming sessions, and stats; it can open achievement solutions from the official Xbox One Achievements app. Users can view Xbox Store purchases and import them into game and DLC collections. Pro users can automate daily updates. A free account costs nothing. TrueAchievements Pro costs $3.99 a month and includes no ads, automatic Xbox syncing every 30 minutes, unlimited on-demand updates, and expanded game lists and trophy case. The site describes itself as independent from Microsoft and the Xbox team.
