The recent editions of the RPG bears the Battletech name, not Mechwarrior. Specifically, Battletech: A Time of War, and its precursor, Classic Battletech RPG. There's also Mechwarrior Destiny, a different ruleset for the setting. All three of which are available on DTRPG. IIRC, Destiny and A Time of War are both still available on paper.
Ah, yes, I'd forgotten they removed the MW title from the RPGs. (Perhaps to not confuse it with the MW computer games?) I have a physical copy of MW2 on my shelves; though I have digital versions of the others the physical imprint of MW still reins strong in my mind I guess.
What makes Voltron different as a setting? (I genuinely don't know. I've only occasionally even heard the name before this thread.)
Adding to what appropriately named MechaAllTheTime said, it's kinda interesting, as Voltron was (much like other series at the time, Robotech being the best known) a conglomeration + reinterpretation of several unrelated anime series to make something for syndication on US television. In this case it was only two series (albeit 3 for the toys), the more popular of which was the "Lion Voltron" from Beast King GoLion. Looking back on it, there isn't much in basic premise of the English version of the show that makes it all that unique beyond a typical "semi-peaceful people are continually beset by evil conquerors", and that these semi-peaceful people have access to a magitech set of very large pilotable robotic lions who can combine to form a giant humanoid who kicks butt every week.
In terms of theme/worldbuilding, the unique-ish aspect would be the series' magitech and semi-medieval-fantasy feel. There are kings and princesses and princes and castles, most of the countryside is depicted in pastoral flows, the bad guys have a witch who cast spells and enchants things, especially enlarging robots who attack and who then are defeated by the lions/Voltron. I don't recall the series having much thematic exploration beyond that, though I was also likely well too young at the time to have picked much of it up if it had.
There might also have been more nuance and themes explored in the original.
Of course, cool stories and character development can well be explored in this kind of setting, and a team that literally has to operate as one in a combiner robot would be ripe for that kind of exploration.
The other Voltron was quite a different affair, being a series about exploration for new worlds, and the team is 15 separate vehicles that can combine in groups of 5 (a land, sea, or air mega vehicle) as well as the single humanoid Voltron. I'm not even sure the local TV affiliate ever played much of this series... that or the Lion version was so much more popular they took it out of rotation.
So I guess what makes the lion Voltron setting different boils down to is being a medieval-esque fantasy knights kind of thing, in a world with magitech and, most importantly, a giant combiner robot.
