How do I make gaming fun again?

[Rainbird]

Well, step one is to realise that it's actually okay to not be all over video games. There's a ton of other stuff out there that's really cool, and even the satisfaction of having your place being reasonably clean and shiny isn't less valid than the satisfaction you might get from playing a given game. If you truly are not that interested in games that much anymore, then roll with it and use it as a chance to expand your horizons! Just don't be stuck in the notion that you are a gamer, and hence you must game; nothing is that static in life.

Having said that, if you do want to rekindle that love, then here's some things I would do:
1) Spend less time with the media - Everything is advertised to hell and back these days, to the point where many games we buy don't hold many surprises for us. And it's easy to blame the media, publishers, etc., but you can reclaim some magic by choosing to ignore all that noise and savour the surprise!

2) Spend less time on forums - Seriously, wading through the Internet day in and day out can be quite the drag.

3) Buy fewer games - As freebs2 mentioned, you don't really get the time to dedicate yourself to a single game. But additionally, choice isn't all that it's made out to be. The more games you have to play, the more you will also always be wishing you were playing something else--something better--than what you are playing now. So stop buying games from Steam sales, Humble Bundles, etc., because it's souring your experience more than it's helping it.

4) Try something new - I talked about how things change in life, and so do your tastes in gaming! E.g. since I finished my education, got a job, and all that jazz, I've started to prefer games that are more relaxed and don't have so many preset goals. These days I'm more likely to enjoy a game where I can take something away from it that I can use in the real world (learning new ideas, seeing things from new perspectives, and so on) than some action pumped AAA title (sidenote: the last episode of Life is Strange is coming out in two weeks, and I'm psyched!)

5) Try something really new - Video games not cutting the mustard? Try some board games! Or some roleplaying! Games is much more than video games

6) Find out what designs you don't like - For me, the word "addictive" has become a warning signal. You'll read many reviews about how games are addictive, but in my mind, that's most likely a sign that a game is catering more to your compulsive behaviours rather than actually being playful. The Assassin's Creed games are a great example of games that will litter the map with stuff to do, but much of that "content" amounts to nothing more than watching numbers go up. Become aware of the design cruft out there and don't be afraid to ignore it, even it means you don't get all the achievements; it just means your experience will be more focused on the stuff that's actually fun.

I'm sure there's more, but that's what I can think of off the top of my head.
