Unofficial Top Ten List in no particular order:

Final Fantasy VII - Can't hold my interest past Midgard anymore, I haven't been able to finish a playthrough in years. The writing is just terrible from Cosmo Canyon onward, and the gameplay balance also gets worse the further in. Great soundtrack though.

Mass Effect 2 - Way over-hyped and not nearly as strong in the world building as the first game. More shooter than RPG for my taste. Mordin and Jack were great but I pretty much hated most of the new characters.

Final Fantasy X - Overly melodramatic with a battle system that doesn't really become fun until your 30 hours in, by which point you don't care anymore. The rest I could say is well documented on this forum so just do a post search.

Persona 4 - Does a few things better than P3 for sure, but also makes some bad mistakes as well. The social-sim part is more fun but the dungeon crawling is more tedious than it needs to be and the story isn't as strong through multiple playthroughs. I also hate the True Ending as it always felt poorly tacked on and largely just redid the more dramatic and better scripted ending sequence to P3.

Valkyria Chronicles - Interesting gameplay that suffers from poor balancing and the Computer A.I. taking it's sweet time to take its turns because it knows its just going to cheese you with the RNG anyway. All this packaged with a bland and overdone "war is hell" anime troperiffic story. It also has the worst menu system I've ever encountered in a modern game.

Golden Sun - Boring story, generic world, and a customization system that always sounded better on paper than in practice. It would have been better had it been an SNES game. It just always feels dated to me, like it was trying to emulate the 16-bit era but made the mistake of inheriting some of the bad traits as well which don't fly as well for modern gaming taste. I hear the sequels are better but the first game left a bad taste in my mouth so I it may be awhile before I ever get around to them.

Crisis Core - "Only good game to come out of the Compialtion" my ass.

Dragon Quest IV - Like three cool characters who become pointless after their respective chapters and a boring grindy battle system that doesn't have something like Job Class or Monster raising to break up the monotony. Story sounds better on paper than in execution but that's kind of DQ's whole schlick. It just had the misfortune of being squeezed between the better entries in the series, not to mention that Final Fantasy finally kicked off its Golden Age around the time this game came out.

Kingdom Hearts II - While it may have the best collection of worlds of any entry in the series, my enthusiasm for it is hampered by the asinine writing; the poor pacing; the "let's make the player go through all the worlds twice!" mechanic that has never been appreciated or liked by players since like ever; and the battle mechanics that are roughly just set up a few support skills and then mash X until everything is dead gameplay that made the game boring. If you've only played KH1 and 2, and you're still somehow excited for KHIII, I can't even begin to fathom how.

Ocarina of Time - Yes I'm counting it. 3D controls are clunky, the best puzzles are just redo's of the better puzzles from LttP, and the new combat system divorces the gameplay into combat/exploring as opposed to the seamless design of the top down Zelda titles.
