Digimon World (PSX, 2000) : Flawed and bugged, but one of the most complete game I have ever played. I played it once a year since I was 10 years old, and 3-4 years ago I still learned things about the game.
The World Ends with You (DS, 2007) : Tetsuya Nomura's masterpiece. The game's "flaws" are mostly subjective, most notably choices concerning the OST, but they make for the perfect setting. The plot is Nomura's best, the 2D graphics are not only but beautiful but also stylish as hell. I want to play it again right now.
Lonely Yuri (Kodoku ni Kiku Yuri, Windows, 2011) : My favourite Visual Novel. It's incredibly short (2-3 hours), and it's a kinetic novel so it doesn't have any choices or interaction other than click-to-continue, and I could talk on and on about how perfect the sprites and CGs are, or how great the light and relaxing background music is; but all that really matters is how much the story touched me. I can't explain why this light hearted story touched me so much, and I know this game is definitely not award-worthy, but I loved it.
