Roads won't give you a lot of xp now. I was planning to level up fast with it but now I am stuck at Digital Age for at least a year I think. I don't know if I 'm that patient.
I understand that replay system recreates the battle in real time from data instead of recording it as a video file. Good idea, despite certain problems I saw, like wrong base layouts and incorrect results. Hope you will manage to solve it. Good luck
Sandbagging is the only thing that will probably make me stop joining world wars. The most irritating thing regarding it is that the system often threat sandbaggers as a weaker team and give them a lot of points for winning. Today my team will lost more than 700 points of prestige in such war.
