1) THE SETTING Almost all space scifi leans heavily on aliens, but BattleTech is one of maybe two or three properties I can think of (the Expanse?) that only has humans - and shows how glorious and awful we are. From the very beginning of the fiction, the House Books, the writing made you FEEL as though the human race had spent four hundred years expanding and the next six hundred squabbling like children, with deep ideas and lots to explore. What made it even better was the pre-planning involved; the return of Kerensky's children was heralded from the first setting books, so the Clan invasion didn't feel forced or surprising if you'd been paying attention. The original devs applied that planning to all of BT's big events til past the Jihad. 2) STEED AND ARMOR AS ONE The central characters being neofeudalistic space knights whose armor is also their steed is BRILLIANT as well. The conscious lean more towards the gritty tanks-on-legs aesthetic inspired by FotS Do
