On the game's subreddit, user UCA_Cash_Flow_Bro compared both projects, calling FFX "a must-play" and even better than Clair Obscur. He called the latter "Final Fantasy X of our generation."
Fans agree that FFX and Clair Obscur share a similar structure, music, and atmosphere. Both games touch on themes of death and acceptance of loss, which also makes them kindred spirits. User Anghellik noted that both "strive for a melancholic tone," and TheIncredibleHork added that the themes of "difficult circumstances" resonate well in Expedition 33.
Final Fantasy X stands out with its turn-based battles and numerous side quests, such as mini-games, which are also found in Clair Obscur. They hide powerful weapons and items for character upgrades.
