I'm in the home stretch with IHW:SC. The last major thing to do is run a final spell check and generate the index. I finished up the alternate fighter combat system last night, It's more different from the aerial dogfighting than I anticipated at first, but I've retained the fun factor. Instead of discrete maneuvers, I have a set of Primitives which can be combined into ad-hoc maneuvers, with the limit being the pilot's skill rank. This system works only for small craft, and the smaller the craft, the better. Something the size of the space shuttle (100 tons) is the limit.
This alternate system is as soft as a grape. That's OK. The do-it-yourself ethos I've run with in IHW:HC means I'm not in control anymore, so folks might as well please themselves. The breadth and limitlessness of the game is leaving me breathless. It's topping the scales at about 412 pages, and it's absolutely packed. If you use this with StarCluster 2, the opportunities should be mind blowing.
