Im yet to play XC3.
I liked XC1 and so far is my favorite in the franchise, Liked the setting and story, but really hated the characters and specially the childish dialogue, so all in all, despite me liking the game as a whole, cant help to feel its overrated.
I absolutely hated XC2, which is why im keeping from XC3 for the time being.
I liked XCX but boy is that a very divise game for me, I liked the setting, I loved the skells, but characters and story are very bad. Very quickly you stop caring about them.
