The 4X game Civilization VI. The latest New Frontier pack is the penultimate release in this year-long run of micro-DLC packs, with the final pack due out in March.
In April, however, the developers at Firaxis have confirmed that they will be embarking on a sizable civilisation balance update. During their most recent developer livestream, they stated in chat that they plan to tackle roughly two-thirds of all of the civs currently in existence in Civ VI.
By the time the final New Frontier pack releases, there'll be 50 civs in the game in total, so we can expect to see changes to between 30-35 of them based on the dev's original statement. There are plenty of Civ 6 leaders.
There are also some from the recent wave of new civs that feel overpowered, so perhaps some of the balance changes will aim at normalising these additions. There's plenty of speculation on both CivFanatics, and the r/civ reddit thread where 'SemiLazyGamer' managed to screen grab Firaxis' comment.
