About
Other sites tell you what to do. We remember what you have done.
What this is
100Percented is a completion tracker, not a guide. Guides are everywhere and most of them are good. What is missing is somewhere to keep your own state: what you have ticked off, what is left, what you can still lose, and how close you actually are to a real 100%.
The first title is Grand Theft Auto: Vice City (Definitive Edition). Every mission, collectible, activity, business and achievement is tracked in one place, and ticking something on any page updates it everywhere.
The No-Surprises Principle
The rule this whole site is built around: you should never be caught off guard partway through a run. If something is missable, it says so, and the warning stays visible even with spoiler-safe mode on. Where it matters, an item tells you what it is, why it counts, how to do it, when it unlocks, and what to avoid.
Losing a trophy 30 hours in because a guide buried the warning is the exact experience this site exists to prevent.
Where your progress lives
Right now, in your browser on this device. There are no accounts yet, which means no sign-up and no tracking of who you are, but it also means clearing your browser data will erase your progress. Every tracker page has an Export button. Use it.
Accounts and cross-device sync are the next major piece of work, and they will be free.
How the data is sourced
Every collectible location on this site is written by hand and cross-checked against at least two independent sources before it ships. Items that have only been checked once are marked as unverified rather than presented as fact. Nothing is invented to fill a gap.
If you find something wrong, tell us. Corrections are the most useful thing you can send.
Who makes it
One person, so far. If you want to write a guide for a game you know inside out, including one you have already published somewhere else, the submission form is open.
How it is paid for
Advertising, and nothing else. There is no subscription, no premium tier, and no paywalled feature. Cross-device sync will be free when it arrives.
