Necrothreading here.
I played OnePageRules Grimdark skirmish not too long ago and OnePageRules Warfleets just a few days ago. I like Grimdark skirmish OK (skirmish rules are a bit crowded and there are others I like better), but Warfleets shows real promise. It played well and there is a new version coming soon that says it will address a few kinks in the system. It is now a key part of a gaming movement I hope to grow called MAGNET which I'll talk about in another thread.
