I think there should be quite a few more inlets, and most mentionworthily, the "sovietstyle" cut off front, with the whole front being an inlet. It could simply be an option for fuselage blocks really, were you have a yes/no button for inlet conversion for the fron fuselage block. This way, when people make replicas they won't have to add any unhistorical intakes, which they try to hide. This would, probably (I don't know anything about developing games) be rather easy to implement, and it would be a nice addition.
Thanks for reading, and what does everyone else think about this?
