From GameWatcher: “Victoria 3 will lean more towards aspects of management than its grand strategy peers in Paradox’s rosters. On the one hand, you’ll have to be more actively aware of the shifts happening in your society, but the recently published dev diary 5 reveals that building upgrades aren also not a straightforward, fire-and-forget thing.

Where other management games opt for linear building upgrades, in Victoria 3, “there are no actions without reactions, and novel innovations don’t just make buildings better with no side effects,” according to the developer.”
