1. Metroid Prime. After 30 hours into the game( I need 3 more missiles for 100% ) I still walk in a room where I’ve been 3 or 4 times before and I still get amazed at the ridiculous level of detail! The whole game is just so complete, as Blade said. I can go on and on about the details and attention found everywhere. Graphics, music and gameplay all come together in the most cohesive and immersive game I’ve played. Damn it! I still waste about a minute looking at the menu screen! BEST MENUS EVER!
2. ICO. Sublime. If you don’t get overwhelmed with emotions and wonder while playing this game, don’t call yourself human

Amazing atmosphere and probably the best sense of scale in any game, I actually felt vertigo in some places. Oh and the PAL version comes with the best and most artistic cover art I’ve seen.
The developers poured their souls into this game and you just feel it.
Shame no one bought the game, no sir, no time for pure art when the “masterpiece†that’s Grand Theft Auto is around…
3. Panzer Dragoon Orta. Fantastic art coupled with technical excellence. It had polish written all over it. In fact it was so immersive and addictive that of course no one bought it!
4. The Wind Walker. Fantastic graphics, amazing gameplay and control and well...polish

Oh yeah! It's a game that actually justifies it's title! The way you have to manipulate the wind it's just ingenious!
5.The Longest Journey. Great story, atmosphere, puzzles, music, characters and an amazing artistic vision.
And a little note. Metal Gear Solid 2 starts amazingly, but IMHO in the second and largest part falls flat on it's face...The story gets really weird (come on! A bisexual vimpire??!) and the interactivity of the Tanker episode is nowhere to be found...And that's coming from someone who bougth PS2 for this game...
