1. Rez - The whole concept of "unlocking" different pieces of the song really appeals to me, who's been heavily into electronic music since 1997 or so.
2. Dragon Quest 8 - When I was a kid, I would dream about an RPG with an expansive 3D world that stretches on for miles, with classic gameplay and gorgeous music. The DQ series is probably my second favorite RPG series ever, and this is just a perfect modernization of the previous DQ games, without deviating from the stuff I loved about the originals - quick and painless combat, large worlds and cool dungeons, a story consisting of many small, clever vignettes... where you don't have to worry about getting bogged down in 30 minutes of cutscenes.
3. ESPGaluda - One of the best and most refined shooters I've ever played. Kakusei mode is such a great addition to this genre, as it makes the endless bullet curtains a bit more manageable. Game also features a nice soundtrack, good mix of trance and video game tuney stuff.
4. Shadow Hearts: Covenant - A great play on the FF PSX formula. Great characters, a nice story, the cool and customizable Judgement Ring system, plus the whole 'alternate history' storyline really appeals to me.
5. Ico - A much more refined game than Colossus, plus the story gripped me more. Beautiful environments and some great environmental puzzles/platforming. The whole feeling of being isolated in a world, thrown there with no idea what's going on, was something that's rarely done in a game, giving me flashbacks to Zelda 1, my favorite game as a little kid.
