I didn't get this notification till just now. If we are only doing the most recent previous consoles I will have a hard time filling the list without cheesing it (Red Dead Redemption!)
1. Dragon's Dogma - For me, hand's down the best console RPG for me was Dragon's Dogma (which only gets better with Dark Arisen). I have sunk hundreds of hours into this game.
2. Xenoblade - I have not had the time to finish it, but aside from so dumb combat mechanics, I really enjoy the world population interconnection and seeing the ramifications of completing quests or discovering secrets and how it affects their relationships.
3. The Last Story - Another one that I have not had time to finish, but again for a JRPG is pretty good. Here are some reviews:

I would have added State of Decay, but that got released on PC.
I started off liking Nier, then hating it, so I would not put it on my list. I can see why people might enjoy it though.
Again though, without including other generations, the RPG choices are pretty light, forcing me to pick JRPGs. I don't own a PS3 so I cannot choose Ni no Kuni, which I have heard great things about, or Valkyria Chronicles which is also supposed to be pretty darn good. If I can include PS2, the list gets really long really fast.
When we do the handheld version of this, boy, there are a lot of good ones out there on the DS permutations and the PSP permutations.
