Europa Universalis 4, Paradox Interactive's dizzyingly rich grand strategy game, will be getting its 17th major expansion, titled Leviathan, on 27th April.
Leviathan is focussed on offering new ways to succeed beyond endless expansion and warmongering, introducing a range of new diplomatic and economic options to meet that goal. "Build a force of diplomats," explains Paradox by way of example, "and use your flattery as a weapon against others. Or draw wealth and power from the remote regions of your realm to construct a metropolis to be the engine of your economy."
One of Leviathan's most significant additions is the ability for diplomats to proactively gain Favours with a nation (previously they were accrued over time), which can then be used to perform useful diplomatic functions - such as abandoning an alliance, or having a nation return a core province - without having to declare war.
