We can only move into the 1900s at this point... Time for some World War action, right!?
I sincerely hope next year's entry is a step back in time instead of another forward. In a perfect world, the nods to 2's main theme in Rogue and now Syndicate would be Ubi teasing a return to Renaissance Italy as a current-gen game could really do the setting justice, but I realise that's decidedly unlikely and so I'd accept any historical period prior to Victorian London that isn't Colonial America.
