I haven't actually played too many of these games. I've played Bravely Default, Monster Hunter, Bastion, Fire Emblem, Pokémon, Dragon Age and Skyrim. I agree that most of these are great RPGs, but I disagree with a couple of them. While I did enjoy Skyrim while I was playing it, I eventually just stopped playing. I just sort of got bored of it. While I do understand that it's designed around exploring, I found that large stretches of nothing around wasn't really conducive to a gripping experience. As I said, I did enjoy it for a while, and maybe I'll get back to it some day, but I don't think that it deserves the #1 spot on the list. I actually enjoyed Oblivion more, though it's not eligible for this like since it's been more than 5 years since its release, but that was because I spent the entire game doing stupid shit with my character, including punching everything with my bare fists, eating everything I could, jumping everywhere I could, and shouting "HADOUKEN" while lobbing fireballs at unsuspecting victims. Yes, my character was a hyperactive Street Fighter wannabe. I thought it was hilarious, and could only have been funnier if I could've somehow simulated the Shoryuken and Tatsumaki Senpukyaku.
My biggest disagreement with this list is Dragon Age Origins. I really hated Dragon Age. Maybe my opinion doesn't matter, since I never really finished the game, but I thought it was completely boring. I did try to read up on the things I missed, so I would be able to see if there's anything else to keep playing for longer. I never felt any weight to my decisions, and I never thought there wasn't one that didn't have a "right" choice; one of them always gave better loot or had more favourable consequences or story implications. I never felt that my party member choices mattered at all, either, because, somewhat paradoxically, I felt that they mattered too much; there's this illusion of choice that's prevalent in the game when it comes to party building, specifically with stats and skills. There are only so many skill points to go around, and there are only so many enemies in the game. You have to be extraordinarily careful of the skills and stats you take, because there's no way to get them back later and no way to get more of them, and yes, it is a problem if you accidentally spec your character in the wrong way. It feels like the game wants me to play it the way it wants to be played, rather than figure out my own way through it. I felt that the relationships with the characters were hollow; there wasn't much at all in terms of animations and sound that really pulled me into the scenes that were supposed to be emotional. Alistair was really the only character that I wasn't indifferent with, and only because I thought he was pretty hilarious. I thought that the setting was pretty meh, too; the Fade was the only new-feeling concept, and that was marred by a horrifically bad level within the Fade. The tropes employed in the story weren't really twisted in any way that really felt new to me, and thus the whole thing felt standard to the point of feeling tragically quaint. The whole game seemed to lack energy, too; there was no excitement at all in... anything, really. The reason for this is that everything is so freaking slow; the combat is glacially paced and felt almost entirely hands-off. It's just attack-skill-attack while waiting for skill to recharge-skill-rinse and repeat, with some healing thrown in there.
TL;DR: I really don't get why people liked Dragon Age.
