Play it like if it is any other Risk Game from RiskGames. Press attack, then select the territory you attack from and then the territory you attack, and then press the right arrow until the number stops incrementing, and then press ok.
Future Changes: I plan on making a string of smaller scenarios where you need to accomplish an objective(such as conquer Paris as Germany for a potential WW2 campaign). I also hope to use the event system already in place in both this game and maybe my own Current Changes: As of now, the only things I have changed is I have changed around the colors of territories when owned by the different factions so as to better represent the potential ambitions of the countries. For example, when France controls Russia, Russia is colored Green to represent the Russian Empire. Also, Prussia's color was changed to accommodate that. Also, if Prussia conquers Austria, then the majority of the territory becomes grey(Prussian) except for the bottom bit around greece, which becomes red(British). This is purely cosmetic, and does not affect gameplay.
