Paradox Interact has released a new developer diary for their upcoming grand strategy title Europa Universalis IV. The dev diary is narrated by project lead Thomas Johansson, who discusses technology research in-game.

Paradox Interactive CEO Fredrik Wester has high hopes for the continued swell of new platforms, providing they stay open for easy innovation and creativity. He sees "four OSes that will compete" for our attention.

They'll be "Windows, iOS, Android" and most likely Linux because of Steam's outpour of support. It's now "really tough" for indies to get on Windows and iOS - more closed now, ending a golden age.
