Hi, I have a game released game on Steam and I've been putting some recent focus into the achievements system:

* The game has six save files, each save file tracks achievement unlocks independently so even if a player unlocks everything on Steam a sibling or friend playing on the same PC can still go for the achievements.
* Achievement visual tracker within each save file.
* Achievements categorised into types such as Enemies, Bosses, etc so its not a giant single scrolling list.
* Have a note on each achievement specifying which update it was introduced in.
* Have the ability to add more achievements, the original game had 20 and the most recent update brought this up to 40. I plan to add more over time as new game mechanics and levels are introduced.
* Also just to note all the achievement artwork is done with Adobe Animate, no AI was involved at all in any of this.

Can anyone think of any other achievement based features or polish that could be included in the achievements system before I start migrating it to other projects, possibly something you wish was more widely available or something cool you've seen in other games? Thanks!

I've been trying to build a feature rich achievement system, what else could I add?
