The other three brothers were not kings for their progeny to become one, Yudhishtir was a king and yet his kids couldn't become one, both are completely different things. Draupadi again maybe be the queen but not the sole queen, not every queen could have their kids on Throne. But normally every king got their kids on throne, something which Yudhishtir couldn't.
Coming to punishment to family even KDDS' family got the same punishment as them.
Karna lost 8 of his sons(the total what 5 Pandavas collectively lost) who were at absolutely no fault, DuryDushy had their entire lineage finished, even Vikarna who supported Draupadi died.
Shakuni's brothers and sons died
So basically all five did get punishments just the nature of punishment was different.
Yudhishtir never"got away" he was punished by Karma, being in the right (or rather winning) side just made him publicly acceptable
