I was reading this article about Neophilia - the tendency for novelty-seeking, and it really rang true about gaming in specific.
A lot of us are constantly chasing the new and shiny. That's the first part of the GWJ Conf Call is all about, after all.
I'm certainly a neophile, not just as a gamer, but it really is in gaming that the neophile tendency hits it's stride.
The article I've linked above has 4 principles for balancing your neophilia, and once again, they really struck a chord in the context of gaming:
1: Regularly interrogate your tastes and run experiments. Remember Elysium's "horizons broadening project" when he hate-played The World Ends With You? Maybe you don't, oh god that was 12 years ago. But it's an excellent example of this, and something I've intentionally engaged in since then. Sure, sometimes you just confirm your tastes (yup, still hate RTS's), but sometimes you find things you love (hello, sim racing!).
2: Choose curiosity over comfort. e.g. List the things you want to play but haven't, then go and play them! That is to say, indulge your neophilia, but with intention, rather than doing yet another raid.
3: Avoid the trap of newness for it's own sake. If you feel it getting out of hand, go on a "consumption fast" for a couple months. We've had "I'm not buying any games this year" threads over multiple years here, and it's always a fun ride watching people fall off the wagon as the year goes on.
4: If your neophilia leads to impulsiveness, consciously add in some time to decision making. We've all made those 3am purchases. At least now, Steam refunds exist to back yourself out of that poor decision.
