1. Final Fantasy XIII (Fainaru Fantaji Shirteen for JPN speakers)-- Best battle system in an RPG ever haven't been this addicted since pokemon gold, amazing graphics/locales (sunleth waterscape FTW), my favorite characters & the way they interacted & were paired up was awesome, surprisingly good music even though Uematsu didn't do it, frocobo, Fascinating world/lore/myth & legends. I'm surprised I liked it for its gameplay more than its story which ends with a feeling of some minor lost potential.
2. Elder Scrolls IV : Oblivion -- Huge open world with its side missions being the amazing part. DARK BROTHERHOOD FTW! The main story was awful but in this game it doesn't matter as you could sink 60 hours into it without doing much in the main story
3. Dragon Quest V Remake -- It blew me away, I never expected a DQ game to be this good, but its a classic. I liked almost everything about it!
4. The World Ends With You -- Fresh music, stunning, captivating gameplay, grippin story. What more can you want!
5. Yakuza 3 tied with Shin Megami Tensei Devil Survivor -- Both good at different things. Yakuza 3 rules for its FUN sidequests & other content. Devil Survivor for its amazing story that was full of twists & turns I couldn't imagine.
As a generation this has been good for me as I finally explored the RPG genre, instead of sticking with Pokemon/FF/KOTOR I got other games & found some gems that shocked me with their quality (DQV).
Others that missed the list -- SO4, DQIV, Dragon Age Origins
