I was happy to see my playtest getting that fast off the ground, though that in part is due to me reaching out to people outside of the DC community.
No question that I personally would love to see another 1648 game being set up since I myself would love to play. But beyond that, my favourite variants are:
- Ambition & Empire (amazing 10-player variant)
- Diplomacy Royale (a rules variant which fleshes out dynastic politics - fascinating stuff, if you ask me. Best combined with a medieval or early modern map variant)
- 1900 (a superior map design than Standard)
And I also obviously enough like my own other two variants:
- Locarno: Europe 1926 (see Dipwiki)
- The Road to War: Europe 1936
