I wish I had more to add, but I can concur heavily with DIVM and Uberhaus.

I'm probably a bit of an odd duck, but out of the hundred plus hours I have in FCCW, I'd say 90% of that has been spent in PBEM matches. I've always enjoyed playing against people more; even if they're worse, or far better ...

I have had no issue finding PBEM games using the official Discord channel.
I haven't tried to host a public game yet, but I suspect somebody would accept rather quickly if I left one up for anybody to join. PBEM system works great.

Hope to see another Winter tourney - just got into the game and was excited to see that these are hosted. Would love to get some experience outside of my usual opponent.
