I'm finding it hard to enjoy any game, no matter how recommended or how well i think its been put together, what the hell is wrong with me?
Lately, I feel like i am just sitting there picking faults until i get annoyed enough to uninstall & install something else.
Somebody cure me.

1)I agree with other posters: take a break from gaming.
2)Related question: does this kind of behavious only manifest in regards of games or have you started seeing only the negative of real-life things as well, to the point of not enjoying given thing anymore?
If it is the latter, you should take care of yourself, as it may even be an (early) sign of depression or some other similar problem. If this is the case, you need strong support from people you have confidence in: tell them about your problem and they'll probably know how to get you back to shape. Also, in this case, try to deliberately do fun, relaxing and happy things.
(I know, it probably has a very slight chance, but better be safe than sorry...)

there is no cure, stop gaming and go ride a bike, go mountain climbing, and then once you're sick of that bullshit, go play a game, n00b.

And as someone who's had depression for 16 years, I can definitely agree that early prevention is better than cure
JUST SAY NO!

I had that thought for awhile when there were just too many crap games out there.
That didn't last too long and I got back to playing games eventually. Even more so than before.

Maybe you've just outgrown games and gaming. It happens. If you like to play stuff online these days, it happens double quick.

I agree with the take a break advice. I game to stress out and do something else other than the boring stuff I do at work, but I also get tired of gaming if done for too long. It's not something you HAVE to do. Do it when you feel like it. The moment you take it as an obligation to play games, it stops being fun.
It's hard to like a game when you are in that state of mind, but once you've rested yourself off gaming and start getting tired of other things, the itch to game might come back and you might look at games you find boring in a different light.
Then again, some games are just plain bad and boring.

I'm on a schedule, actually. At the start of the autumn, I start playing videogames, then I spend all the time 'till winter with them. Some time before christmas, I start to get creative, but it's still related to games in some manner. When spring starts, I get bored so I watch movies and TV shows and then I'm writing stuff 'till summer. And then autumn hits again and ... you know. Then only thing I actually do ALL the time is reading

Maybe your are seeing life in a larger picture and what was once important is less so at this point and time.
I would simply say enjoy all the things in your life and gaming will fall in its proper place in the big picture.
One thing for sure is that our life goes through changes all the time. Games may not hold the central point any longer, but they will likely always have a place in your life.

I always said, I'd probably get it on with the most meh of girls just so long as she took a very active interest in the EXACT same things I do, as well as others.

Uninstall all but ONE game, and treat that game as a casual pursuit at best.
Also, considar trying a new type of game, or a semi-game such as an online flash game, or such.
If you have the normal level of enthusiasm for other aspects of your persoanl and professional life, I wouldn't worry about it. Just tweak yoru gaming behavior and see what happens.

Its a sign of old age, or at least a sign that you are getting older. You'll walk away from games for a while, then get really picky about what games you do get and really enjoy those games in bursts with long lags in between. Happens to everyone eventually.

I think you will not find a better advice.
Even with changing genre of games, sometimes you just feel that every games are the same thing, and in fact it is, all games use the same basic mecanisms but don't present them the same way.
Sometimes, a good thing to do is finding a creative hobby: drawing, painting, even if you're not good at that, just do it for yourself, there's nothing warmest than create something by yourself.
It's the bad aspect of games, you have the feeling to do something, in fact you don't, you just entertain yourself.
Good advice here too, could be a good alternative solution ;)

Have you tried drinking heavily? That generally works for me.
Also, cheese. I love cheese. Especially raclette. Ever have it scraped off the wheel? I forget the word for it.
And cigarettes. But not those delightful, wonderful Djarums, because they're banned by my gov't. *shakes fist angrily*

Say what? I just bought some Djarums a few weeks ago. What state do you live in?
