Fire Emblem Awakening.
Radiant Dawn was still my all time favorite game when Awakening released. The previews were really good, so I even preordered the limited edition 3DS with the game (I didn't have any 3DS back then). The reviews were also amazing so I was really hyped about the game. Biggest disappointment I ever had. I usually finished Radiant Dawn in 3 days because I couldn't stop playing it (I finished it 3 or 4 times), but Awakening took me a year to finish because I couldn't find the motivation to keep playing. I even had to restart the game in Lunatic to find some interest. The focus of the game changed too much, and the TRPG elements were just... absent or bad, especially compared to Radiant Dawn.
Because of this I still can't buy Fire Emblem Fates, even if Conquest supposedly comes back to the original formula. For the first time since I discovered Advance Wars as a kid, I lost faith in Intelligent Systems :/
