Title mostly describes how I'm feeling now.

When I was younger, my main worry when deciding what game to buy and play next was that the game wouldn't be able to keep me entertained until I can buy another game.

Now I have a backlog of almost 100 games that I own and haven't played yet (although some come from bundles, not all are worth playing). My new concern when I'm playing a game is whether or not the time I put into the game is well spent.

I used to really like the idea of games where it would take me 100s of hours to get to 100% completion, but now I tend to almost avoid playing them entirely even if I know I don't care about completion anymore.

I don't think I'm alone in this, but what I'm really wondering is if this is a result of getting older? Or is it because the gaming space itself has changed?
