Should probably be something more like Gothic III/10. Seems more appropriate.
That actually crossed my mind while typing the post. But Gothic III's problems are of a different order than Elex II's. Back then, Piranha Bytes had ambition, they made an excellent map, beautiful music, enemies that weren't always hostile and interacted with each other. They overreached and didn't have time to fill the world with interesting quests and released the game in an unplayable state. Their custom game-engine didn't seem up to the task either, either due to a lack of time or skill.
Elex II doesn't lack polish, it's bland and uninspired. And the writing, while funny at times, completely misses the mark in the main story.
