Although my favourite RPG is Suikoden 2 I'm going to give one to each year of the previous decade. And I will only give one to games I've played.
2000- Suikoden 2
This game was a pivotal game for me both personally and philosophically. It was the first game that I really felt for, the first one to keep me awake at night, and will always remain very dear to me (and my wallet

). This was the game that made me realise games ARE an art form.
HM- Majora's Mask- 3 days to save the world? With Everyone having their own problems on the side? Sign me up. Brilliant game, although not technically an RPG it still is my favourite of the LOZ series.
2001- Pokemon Gold
The final great Pokemon, back when 251 sounded so much better than 649. The only main Pokemon game that included 2 regions. I just feel cheated now with only 1.
2002- This year I haven't got round to playing yet
2003- KOTOR 1
This is when I discovered Bioware. A discovery I have NEVER regretted. Epic game, and I hope to see the same shine in The Old Republic later this year.
2004- Vampire the Masquerade Bloodlines
Probably my least favourite on this list, it's still a brilliant game and definitely worth a couple of playthroughs.
2005- KOTOR 2
Although not made by Bioware, which effected the story somewhat, otherwise it took all that I loved about the first game and improved upon it. Great sequel, which probably could've of outshone the original if the story had been Bioware's.
HM- Psychonauts- Again not technically an RPG still a brilliant underrated game of the year. I'm hearing slight rumblings of a sequel, which I hope are true.
2006- Oblivion
I'm not sure any other game could've taken this spot. This game introduced me to the wonderful world of modding. Seriously with a solid enough mod base this game ages REALLY well. And of course The Shivering Isles Expansion, is probably my favourite expansion of all. With predecessor like this who can't get excited for Skyrim.
HM- Lost Magic- Again not an RPG. Still a good game. Using the Touch screen to the best i've seen so far, and the combo's of magic was just... FUN.
2007- Mass Effect
Bioware re-enters this list in triumph and creating what I consider the most consistently best series so far. And of course Commander Shepard.

Need I say more?
2008- Persona 3
This year was a good year for RPG's and it was tough to pick one, but it goes to Persona 3. For having just a great host of characters.
HM- Fallout 3
The strengths of Oblivion came back in Fallout 3, mods and expansions. This was the first time I felt a game might be TOO large. Of course if we are talking recent game size, Just Cause 2 is SCARY.
HM- Fable 2
Best of the series easily, and the final choice was something that I found personally difficult.
HM- Lost Odyssey
At a glance this is just a cliched JRPG. But what truly shines are the short stories or "memories" one can gather throughout the game. Plus Jansen was funny.
2009- ???
After the high of RPG's last year came the low of 2009. Batman: Arkham Asylum (I'm looking forward to the sequel as well) and Assassin's Creed 2 (Again looking forward to 3) being the best of the year.
And no COD doesn't deserve to be anywhere near this list.
Even as an HM, the ONLY good thing about it is that it has a HUGE player base, meaning online multiplayer is just short of an MMO.
Mass Effect 2 2010
THE ARPG, yes it may have lost a lot of its RPG elements from the first but it makes up for it in action, and there is still the Bioware shine of story, dialogue and characters.
My only real fear is Mass Effect 3, most specifically it can be summed up in two letters. EA.
Don't ruin the series, it will be one of the biggest shames of the genre and the companies if this game sucks
2011- We'll see.
With Skyrim on the horizon, and Mass Effect 3 pushed back to 2012, I think Skyrim will sweep 2011 RPG.
I'm kind of glad Mass Effect 3 got pushed back, I wouldn't like to see 2 of my good friends slug it out.
Of course if MMORPG's are included as well, The Old Republic might put up a good fight, if it's released this year.
Anyway that was the last ten years, here's to the next.
