I've actually had 2 straight years of peace right now in Arthurian TW.

I'm playing Goddodin, I'm allied to Ebrauc and Alcuyd. Neutral with Rheged but have trade rights (crushed the buggers in a year and a half, took three towns and sacked their capital, they accepted unconditional peace), and neutral with the Picts (although the picts have been at a constant state of war with my ally Alcuyd, and we fought briefly for a time before I sacked their capital too, hahaha).

Oh..and then there's Ynis Manau, once a decently powerful faction that my ally Alcuyd absorbed all but one province of. They landed an army on my coast once to try and take a town but were duly crushed, and subsequently offered me a peace treaty. I had no land borders with them, Alcuyd had absorbed them almost completely, and I had no interests in building a fleet solely to attack their last province....an island province.

I've been playing with the no retraining units rule and the must have one ship per unit rule like we do in the pbem here, because it's more fun to me, and a bit more challenging.

I'm actually kind of disappointed, I'm so happy that I'm not completely surrounded by horribly hostile nations, I almost don't want to declare war on anybody...but the picts are getting a bit too strong, and I think they're due for another sacking in a year. They had lost two provinces to Alcuyd but have recently taken one back and snatched a few rebel territories too, so I think it's time to put them back in their place.
