The Nintendo Switch has no built-in achievement system, so I built one called Completionism (free, no ads)

Nintendo Switch doesn't have anything like Xbox achievements, Steam achievements or PlayStation trophies, so a while back I started hand-compiling per-game 100% completion checklists for my own games. It eventually turned into a full site: Completionism (completionism.ca). The idea for the site itself was inspired by Steam achievement tracker websites that rank users amongst other users based on what achievements you've completed and for what games.

What it does:

• Browse a catalog of Switch games and build a personal library (Interested / Playing / Completed / Dropped)
• Each game gets its own hand-compiled achievement list: real, verifiable completion criteria, not just "beat the game"
• Checking off achievements automatically updates your library status, and some achievements auto-complete others they imply (e.g. finishing the top tier of a collection auto-clears the lower tiers).
• A global Achievements browser to search and filter across every game in the catalog

It's free, no ads, and not affiliated with Nintendo whatsoever, just a fan project for completionists who like actually finishing their games and want that extra sense of gratification.

Coverage is still growing since every achievement list is hand-researched rather than scraped, so if a game you care about isn't in yet, or you spot something wrong, there's a feedback page for it. There's also a Discord if you want to suggest games or report issues directly, and join the community.

Would love feedback, especially on which games to prioritize next. If you like the project idea and know any completionists yourself, feel free to share this post or the site itself. Soon to come will be a verification process which will tie into global leaderboards for those competitive gamers out there.

Figured I'd post this here as this seems like the most fitting community for what this project entails. Hope it reaches the right audience!
