Yeah... but....I note you said "space flight sim", not "space combat sim". There is a big difference. If all you want to do is trade and explore, spending hours doing combat is not fun, and a waste of time. If combat is your thing, learning combat is necessary, but you may think exploring and trading are boring and a waste of time. One of the things I've heard most about ED is play it your way. A player shouldn't have to spend hours learning a part of the game they are not interested in.

Which isn't quite how it works out - but the combat has never ever been suggested as something you could totally avoid. Learning to defend yourself is a minimum requirement of survivalPirates may even await intrepid explorers returning from afar, threatening them with destruction if they don't hand over their data.
