Probably going to be an unpopular opinion... but I really wish there was some prequel planets in this game.
Despite a lot of things the prequels does wrong, and the overuse of CG, those planets are far more interesting to explore in a game, imo than planets that were created using on site filming and practical effects.
For example Cato Nemodia, Kamino, Courascant and even Naboo all have interesting architecture and environmental features
Opposed to the original + Force awakened planets which are essentially Hoth, Tatooine and Endor, plus sullust and later Jakku.
Hoth Endor and Tatooine are essentially just snow, forrest and desert maps. Sullust is probably the most interesting in the base game, and Jakku could practically be indistinguishable from Tatooine if it wasn't for that star destroyer.
In a film, over use of CGI is bad sure, but in a video game those fantastical worlds are ideal.
