If this is anything like DW5 Empires, it's gonna get old quick. I got all the achievement points, unlocked all the characters, etc and I was STILL unlocking new commands to execute. Some people might like this, but I find it annoying. Plus, battles got boring when enemy generals kept reappearing after you defeated them over and over again.
That and it's been at this point since like week. Like L4D2, it didn't go back up, probably won't until after chirstmas or something.
