One of my gripes with TFA (which I like a lot overall) is that there were almost NONE of the existing alien species represented and a bunch of new species. I don’t think that the time jump of just thirty years would cause the extinction of alien species...

But so far in the Mandalorian we have gotten lots of classic Star Wars species represented already! Quarren, Trandoshans, Jawas, Ugnaughts, etc. It actually feels like the same world as the original trilogy. Maybe I’m just a KOTOR fanboy but I would love to see some of the other existing species too as the series goes on, Ithorians, Mon Calamari, Twileks, etc.
