A little while back I launched EU4 Strength Score — a small tool that scores your Europa Universalis IV achievements by how hard they actually are (per the wiki's own difficulty ratings, not just how rare they are on Steam), and recommends what to unlock next.

It got a genuinely warm reception, which was a nice surprise. That was enough of a nudge to try doing the same thing for other Paradox games, so Victoria 3, Hearts of Iron IV, Crusader Kings III, and Europa Universalis V all now have their own Strength Score sites too, built on the same idea.

Achievement ChainZ itself actually started as an early attempt at a general achievement-centered app, without any one specific shape in mind for it. Turns out it fits well as a platform for tracking the achievements that sites like EU4 Strength Score suggest to players — so I connected the two. The achievements EU4 recommends you chase next can be turned straight into a chain that opens right here in the library, and clicking any individual achievement on eu4.jane.berlin now takes you to that achievement's own page in this library, instead of just a plain wiki link.

If you haven't tried EU4 Strength Score (or one of its siblings) yet, give it a shot — and whatever it suggests for you next, you can follow it here as a chain.
