Victoria is from Paradox Interactive, makers of Hearts of Iron, the primary difference being that it covers the 1836-1936 timespan instead of 1936-19... umm I think HoI goes up to like 1950?
Anyway, Victoria is the final boss of real time strategy games.
Italy game I started with V1.1, doesn't really work anymore though...
This is why... 44 infamy lol... Britain & France declare war if I attempt to play it now.
Current Austria game
