when all the remasters/upgrades are done you gotta re-master the banner for the game :D, the artist truly is one of the best out there when it comes to this style.
also will you have different outfits for them? I think that'd be nice. dunno rly how well it'd fit into the game with the story but a change of pace and also shows that they are more like people than just robots. but I kinda doubt that, it'd be kinda hard to write? also giving more work to the aritst
