Forcing yourself to finish a game

Alan Wake was the most recent game this happened to me with. Picked it up last summer, played through the first three chapters and didn't get around to finishing it until last month. That sad thing is that I only finished it because I felt I HAD to to justify the purchase I made many months ago. Bleh.

For some reason I have a really hard time finishing Bioshock.

INFamous was a game that I basically forgot about completing. Then I did complete it, and started a new game because I enjoyed it that much.

I'm currently forcing myself to finish Star Ocean: The Last Hope (x360) right now.  I played Star Ocean: Second Story back in the day and really enjoyed it, so I bought The Last Hope on day one hoping to rekindle that love, however I never made it off the first disc and stopped playing completely about 20 hours in.   
 Mostly because I had a extreme dislike for a few of the characters around that point in the story, namely Edge the main character and the only available "healer" party member at that time, Lymle.  Emo shit is not my thing and neither are annoying baby voices. 
 
Anyway I came across this game in a box of old games like two weeks ago and felt bad for totally dish-ragging it two years ago.  So I started over and suffered through the terrible voice acting and strange choices in western localization.  I'm about 35 hours in now and starting to enjoy it more and more as the story progresses.  Dare I say, I  might not be forcing myself to finish it soon?  I found some good party members to fight with (Meracle, Myuria and Reimi are my dream team), allowing me to reduce the time I have to hear Lymle speak.  Edge isn't as much of a lame emo child anymore either.  So if you're suffering through the game at around hours 12-20 as well, don''t worry, keep at it, and it'll get better. 
 
Side note:  Welch is the best character ever!!

I had to force myself to finish Fallout New Vegas after screwing up the story.  Not much of a spoiler but if you kill the Gomorrahs outside of a mission the game becomes extremely screwed up and became a chore.  I wanted to finish just to say I did but I plan on giving it another try because I adored Fallout 3 and all of the expansions.

Final Fantasy 13, but I got fed up in the end.
 too bad, I wanted to see the ending.
 
You got tired of Bioshock? damn :(

Too Human and Hydrophobia. I really don't like those games but I just want to finish all the games I get so I forced myself through them.

Alpha Protocol took some willpower to get through.

I sort of had this problem with The Darkness.  Cool game, lots of awesome moments.  But for some reason I tend to put it away for months at a time.
 
And with GTA IV, I tried coming back a few times but I don't plan on trying again.

" @Dad_Is_A_Zombie:   Oh shit I have to do that too. When the RTS parts started I just quit. "

Resident Evil Code Veronica X, I felt the game was far too long and drug along up until th end, but I forced myself to play it, simply because it was a Resident Evil game and the only game I had received for my new PS2 on Christmas.

I hate that dilemma. If I start playing a game but drops off at some point, I just can't start playing a new game and really immerse my self in it. Need to have "clean sheets".

Achievements/trophies kind of help, gives them a tad more meaning. At least in my case. Also helps being sick! Cuz when you ain't in the mood to play good games, play crap and get over with it!

I've had a few titles making me feel this way, which is a damn shame. A waste of money if the games aren't fun.

I also felt the same way towards Resident Evil 5, played and loved RE4 but for some reason this one didn't do it for me and I beat it out of guilt for not finishing it when I left it half way through. Halo: Reach was the same which I just recently finished after first getting the game back at launch. One day I'm going to try real hard to finish those Legend of Zelda games I left half finished. 

If you are not having fun then why force yourself to keep playing something? 
 
As for RE 5 specifically, just put it on easy mode and burn through it. I did it on the PC in one sitting, about 5-6 hours iirc, so it can't be that hard. It was a very bad game that I wouldn't wish upon anyone, but if you want to see it play out it shouldn't be too hard. It was my first and last RE game that I will ever play too.
 
I just did it because I always wanted to see an RE game to completion, as I always heard people talk about them like they are the greatest thing ever. I guess it's just another game and franchise that can get added to my pile of "Why the fuck do people like this shit?" Each their own and all that.

I had this with Far Cry 2 :(

Darksiders, just wasn't feeling the art style and game play. Playing through twice to gather all the achievements. I blame myself for that cause normally I just role with a game and halfway through I look at the achievements.
