Even if they don't address them in the initial launch of Genesis, I hope they address them in the next episode of the new game because 1000 years seems plenty of time for Draconian and Lillipans to become a part of ARKs whether it'd be simple citizenry or part of the main team.
While it would be nice for them and the rest of the aliens become playable races, I don't mind if they're still regulated to being just costumes for players to dress up as. I just want to see them still being around in the game and possibly be NPC allies. Like I wrote, it's not something that I want to see immediately when the game launches, especially if it's something that never crossed their minds when they made the game and still working on the finishing touches, I just ,at the very least, want them to still be around in this universe and at least relevant to the plot even if it's a sub-plot.
