Returning to the Battletech fold after about 25 years. I've been looking into the aerospace side of things, since that's something that always interested me but I just never got around to. Started reading the Total Warfare aerospace rules, and after days gave up - aerotech rules poorly organized, scattered here and there throughout the book. Aerotech 2, however, seems very straight forward - cleanly organized, no ground rules breaking up the aerotech chapters.
So the question: how different are the two rules sets? Is it possible to use Aerotech 2 rules with Total Warfare era fighters and ships of various classes without any redesigns? (At least until they give aerospace the Battlemech Manual treatment. ;) )
