The two on the grid
Compare the whole catalogueHearts of Iron III and Hearts of Iron IV on the axes the GamingPickz Score is built from, on the full 0 to 100 scale so each dot is its real position. Change either axis to compare them on any measure.
2 games have both
Players. The share of Steam reviews marked positive, pulled toward the catalogue average in proportion to how few reviews stand behind it. A game with 200 reviews moves a long way toward the average; one with 200,000 barely moves at all. Without this a title sitting at 100 percent on nine reviews outranks Half-Life 2 at 98 percent on 278,000.
Popularity. A blend of two things that are not the same. Audience is how many people wrote a Steam review, which is a floor on how many played it. Reach is how many language editions of Wikipedia document the game, which is cultural footprint rather than sales. A game can score high on one and low on the other: a huge free-to-play title has audience without reach, and a landmark console exclusive has reach without a Steam audience at all. Where both exist they are averaged; where only one does, that one carries it.

How positions are decided
No paid placement, no favouritism, live third-party data
- Placed by the published method, not by us. Every coordinate is computed from the axis definitions and weights printed on this site. Nobody moves a point. See the axes.
- Nothing here is paid for. No sponsored placements, no promoted slots, no arrangement of any kind affects a position. If that ever changes it will be labelled and sit outside the ranking.
- No favouritism, including our own. The 16 games we have written full reviews of are scored by exactly the same formula as the other 1,510, from the same third-party inputs, and they land where it puts them. Our own opinion of a game does not enter its coordinates.
- A position is not an endorsement. It says how a game was received and what it costs, not that we recommend it. Where we do recommend something, it carries a written review with a name on it.
- Fetched from live third-party data. Player sentiment from Steam, critic aggregates as published on store pages, prices checked hourly, attention from Wikipedia. Each figure carries its source and the date it was read, and we do not adjust any of them.
Which to pick, by what you want
- The higher-rated of the two: Hearts of Iron IV (GamingPickz Score 8.4)
- The cheaper right now: Hearts of Iron III ($9.99)
- Better on a Steam Deck: Hearts of Iron IV (playable)
- The safer bet by weight of reviews: Hearts of Iron IV (375,658 reviews)
