For those of you interested, IHW:SC is now back in playtest. I am very happy with all the changes I made, and I think I have covered everything. Chargen is pretty much the only thing that hasn't changed since the previous playtest. I am *much* happier with starship and vehicle combat! Virtually everything is extremely customizable - clusters, worlds, aliens, ships, vehicles, and of course, characters. No two games will ever be the same, but the feel of StarCluster will be there. The use of traits throughout lends a consistency to everything. I wish I could have used the same combat system for vehicles and spaceships, but I couldn't do that and keep the physics based feel of StarCluster.
That was the important point for me. I could have a military game, but it wouldn't be StarCluster if it didn't feel right. These customizable elements end up feeling like a part of StarCluster that I never designed, which is just perfect!
