The main game itself can be completed fairly quickly, within 10 hours if you were really motivated and ignored extra loot, cosmetics, & “hidden bosses”...
Unless you’re a fan of Star Wars, this game will leave you mostly unsatisfied as it is rated a 9/10 on steam, but mostly feels like a bunch of diet mechanics from other games (GoW4, Prince of Persia, Sekiro/DS) with a Star Wars theme draped over the top.
Average game with fun moments and serviceable story, not worth the full retail price (definitely buy the game on sale, in a bundle, or as part of some subscription/Game Pass).
