    2,978 mentions Positive Neutral Negative

    • “Deep and complex lore, addictive and fun gameplay loop, no microtransactions, and full of heart.”

    • “Franchise has now turned into a cash grab, and you, the gamer, as well as the people who made this gem, are the ones getting screwed.”

    • “Character development: non-existent.”
