How grim is the RP supposed to be and what is the 'morally brightest' faction?

Battletech's not as over-the-top grimdark as something like 40k, but depending on the era, things can get pretty messy. During the time period this game is set, the late Succession Wars, overt warcrimes like WMDs or direct attacks on civilians are pretty rare and a major scandal when they happen. That said, collateral damage does happen. Think along the tone of most Gundam series set in the One Year War timeline; generally Battletech rarely goes beyond PG-13, with the truly nasty stuff only implied rather than shown directly.

As for the most morally bright faction, that really depends on who you ask. In a lot of the earlier novels, The [url=https://www.sarna.net/wiki/Federated_Suns]Federated Suns[/url] and [url=https://www.sarna.net/wiki/Lyran_Commonwealth]Lyran Commonwealth[/url] (House Davion and House Steiner) were generally considered the 'good guy' factions, but later novels sort of rounded everyone out. I'd honestly say the closest thing to a full-on Lawful Good faction in the Inner Sphere are the [url=https://www.sarna.net/wiki/Eridani_Light_Horse]Eridani Light Horse[/url] or the [url=https://www.sarna.net/wiki/Kell_Hounds]Kell Hounds[/url].
