Since this has come up a couple of times, I just wanted to point out that
you do not need to play any actual warhammer games to take part in the campaign! While these games were usually required for earlier campaigns, I realize that not everybody has time to play a game every week. So you don't need to! Instead you get to report once per turn, regardless of whether you've played a tabletop game or not.
Of course, written battle reports can still earn you some extra gold, but the same reward can be earned with stories, pictures of models you've painted etc...
So, if you considered joining but worried about needing to play a game each week, then I can reassure you. Wartales is open for anyone who wants to join
