A Decade of hearts of iron iv

A word from the Hearts of Iron IV Team

A decade. It still feels strange to write. Hearts of Iron IV turns ten this month, and somehow the most unbelievable number in our telemetry isn't the millions of techs researched or wars declared, it's this one: 39% of the people who started playing HoI4 back in 2016 are still playing today. Ten years on. Another is that HoI IV has been going on longer than WW2 actually took: 2194 days for WW2, 3652 (and counting) for HOI IV. The game has changed enormously since launch: most mechanics have deeper experiences, focus trees are very different and much more exhaustive, the AI plays the game better, and we are able to keep closer to the historical timeline than ever before. But the core vision, as described 12 years ago, still holds true. One thing we did not necessarily foresee, even if it was a core part of the vision at the start, was the adaptation of mods to the degree we see today. We’ve also seen two Game Directors transition to new internal projects, and we will talk about who will take over on June 18th! To every player who has shaped this game over the last ten years, and to every developer past and present who has poured themselves into it: Thank you. Here's to the next decade. /Niels Uiterwijk - Studio Manager
