Don't know, sorry, haven't played any of the fan made campaigns. I sometimes play scenarios with my friends on voobly. Norse Wars and Food, wood, gold are both good.
@clam_chowdah We are able to play our games at 19:30gmt Friday 15th. If that doesn't fit into your schedule, I can stream the games, and post them here.
Edit: most likely can not play at arranged time, will attempt to re-organise.

If you have a clan of six or more people, sign up for the Hybrid Cup. The main RTS-league will follow this tournament.
