So, my wife and I both enjoy video games. We used to go by this local media store every Sunday to dig through the games they had and pick up stuff. It was a glorious time and many awesome deals were had from NES to PS2 all at what would be considered amazing prices.
At some point though, I became a bit too focused on the collecting aspect and started to get more and more stuff that I wanted to play and mess around with online. I would buy in lots with the goal to keep some and resell the dupes, but after awhile I discovered I was not really selling much or very fast. It wasn't really that big of a deal until we had our daughter and that definitely changed the math on extra funds available plus brought to light how much we were spending.
I have continued to collect and play but have slowed down a lot on both fronts, and my wife still plays some games but not as much anymore. We had lots of weekends before where we would just veg out and play all weekend and plenty of gifts giving were gaming related. That still happens to a degree (I had preordered the Ni no Kuni Wizard Edition for her when that came out and she was ecstatic to receive it), and if she does feed my habits rarely it is something small and Sega or Sonic related, never PCE.
But, I think the main thing is our lives are both shifting away from games to a degree with my daughter now 2 years old. It's still a part of our lives, just not as much focus as previously, and I'm personally trying only to purchase things with funds derived from selling off other stuff.
