A lot of games have always been shit, that's not new. It's easy to look back at the games of old with nostalgia and think "wow, games were better back then", but really you just don't remember the mountains of trash games that came out.

Also, you have to reckon with the fact that you may still want to play the same types of titles, but you don't have the time anymore to dedicate to actually enjoying it. So you have to adapt your game choices. For example, I really love turn based strategy games like Civ, but I've bought a few recently that I haven't played for more than 10 minutes. I realized that I just can't spend the hours it would take to learn the strategies and controls like I used to when I was a kid.

This is why I keep turning to old games like Alpha Centauri or the original Fallout games: I already know the rules, I know what to do, and I can just jump right in for an hour and not have to spend the first 55 minutes figuring out how that shit works.
