I will give another vote for FFXIII, I came into it with low expectations but hoping to be surprised and I was surprised by how bad it was. It was basically the video game version of watching a movie that sounds promising and you keep watching despite not liking it because you hope that at some point it will pick up and then you reach the credits and realize it didn't. I still can't bring myself to play through it again and to this day it's the only non MMO FF I have yet to play a second time.

Fallout 3 was another game like that where I kept waiting for it to get better and instead got lost. While some stories were interesting, the game got too easy rather quickly and the main plot just feels pointless. Due to getting lost a lot, never using a guide, and long bout of not playing it took me years to actually finish this game.

Star Ocean First Departure, I've been chipping away at this game for awhile. I think I'm only still going because I feel I am towards the end of the game but good lord has this game not aged well and even updating to SO2 gameplay/graphics can't really save it from it's silly plot and boring cast of characters.

I will also mention Assassin's Creed 1 which is way too repetitive, restrictive, and surprisingly easy. I think the story was the only thing that kept me going through that one. Brotherhood was the other that gave me issues as the story felt forced and the gameplay was pretty buggy.

Suikoden Tactics, good lord I tried to like that game but I just can't. It has some good ideas but it's also filled with some really bad ones as well and like it's companion game Suikoden IV, the title just felt half finished. It feels almost if sometime after they finished the game someone just went in and edited out a bunch of plot and story elements in order to make the game in the 40 hour range with no real thought about how it would affect the pacing and characterization. The hit-or-miss VA work certainly didn't help either.

Crisis Core was another I played through partly because I liked Zack and partly because all my gamer friends insisted it was really good and emotional and just... ugh... it's so damn repetitive and easy and it's just like FFX where all the challenge is just mindless stat min/max with no real benefit. The plot is pure fan-fiction with Genesis and just...ugh...

The ultimate winner goes to Final Fantasy X for me, the first time I played it, I was just happy to have a bright new FF for my new PS2 and I tore through it to gobble up the plot and characters. When I finished it, I was left a bit underwhelmed, but whatever I had MGS2 to playthrough a dozen more times. My second playthrough, I really focused on the gameplay side of things, and that was when I really discovered that part of my nagging issue with the game was how utterly boring all of it is. Once you know how the story goes, you start noticing how mediocre the rest of game design was; and even though I spent time doing the Coliseum and completing the Sphere Grid, I realized it was all meaningless because you can't really focus on either until you're near the end of the game and even without grinding or ultimate weapons the final boss is easy. My third playthrough was against my will and largely forced onto me by my current girlfriend who wanted to see the game ending but lost interest in playing the game for largely the above reasons. She loves X-2 and so she felt obliged to see the ending and forced me to make it happen. It was this playthrough that made me realize how utterly pointless the equipment system is and I noticed more holes in the battle mechanics as I quickly decimated my way through the game with largely starting gear, minimal grinding, and abusing the hell out of the Overdrives. I've probably put over 150 hours into this game over three playthroughs and I swear I'll never play it again, I don't give a smurf about Penance or your Dark Aeons, go kick a landmine shaped like a blitzball.
