I've heard some people say they fell off gaming around this stage in life and then got back into it after a few years away. So to you gamers who are older and wiser than myself, is this normal? Am I slowly falling out of love with gaming or do most people tire out around this time?
Warning, OP: long post incoming.
First of all, I'll say this: I think having an ebb and flow to hobbies and interests is a normal and healthy thing. You can go through phases of your life where you focus your time and effort toward different pastimes. Nowadays, I'll have some years I'm really into sports, other years into outdoor pursuits and socializing, others movies and TV series, and others video games. It sounds like you are filling your time with enjoyable things and expanding your interests - that's great and there's nothing wrong if the time and desire for gaming just isn't there for you right now.
Second, if the time barrier is a real issue for you where you feel like you can't play games unless you have a big block of time - well, you'll have to get over that and figure out a way around it. As you get older, having a free block of time and the accompanying mental bandwidth to play for 5+ hours is very rare, at least from what I've seen and experience. You have to get mentally comfortable squeezing in shorter sessions during the week and focus your "longer" sessions during certain weekend time blocks. If you're playing a short to moderate length game, smaller playing sessions through the week add up. Playing for 45 minutes a night during the week may seem hardly worth it, but that means by the weekend you're about 4 hours further into a game.
As for my ebb and flow with gaming:
I was a big gamer from being a child through high school. Even when I had a full social calendar and played sports in high school, I was still carving out time to play all manners of RPGs, action/adventure games, fighting games, etc. Through my four years of college, I was too focused with my social life and school events to do much gaming. I did some light gaming, though; mainly multiplayer Halo the first couple years, and then the last couple years regular sessions of online multiplayer in NCAA Football and I played the three PS2 Grand Theft Auto games.
When I was in grad school, I picked gaming back up in a big way and it was a regular hobby of mine for about 6 years thereafter. Then around the time the PS4 was being released, I stepped away from gaming entirely:
I basically didn't touch a controller for about 5.5 years. I barely even followed gaming news during that time frame. I kind of thought that I'd never return to console gaming as a hobby in any real way.
Then one random fall night in 2019, I got the itch to see what I had been missing and read up on a bunch of the PS4 games that were released over the past 6 years. I ended up buying a PS4 that next month during a Black Friday sale. From then until now, gaming has been a regular hobby of mine again and I don't think I've had so much passion and enjoyment for it since I was a kid. I even managed to snag a launch day PS5, and I'm not someone who ever gets launch day hardware. My enthusiasm for gaming again even caused two of my friends to jump back into the hobby in a serious way this year.
So, yeah, decreasing the time spent on gaming as a hobby, or stepping away from it fully for a while, can happen. It may even make you enjoy gaming that much more when you eventually return to it.
