If you do not enjoy your hobby I would suggest finding one that you do. What is the point in a game you don't play? A book without words, a song without sound.
My point isn't that games arn't worth while, only that like a book or a song, not all of it is going to be good. In the case of games, ALOT of it isn't good because if the perceived value is in the length of the game, they're going to dot it thoroughly with small grindy bits..
It's like reading tolkien , just read the cliff notes.. watch the movie, read some reviews and you're done.
For quite a while now (since xbox360 probably) I've generally preferred shorter games, usually indie stuff, because I rarely want to spend 10+ hours on a game. Stuff like Inside and Gone Home are perfect to me cos I can do them in an evening and have a powerful experience. Or arcade stuff like OutRun for short bursts. I'll put big hours into really special stuff like GTAV or Zelda BOTW but it's rare, like once every couple of years. It's not like when I was a kid/teen and wanted to find every secret in a huge game. I remember taking time off work when OoT came out. I seem to have a bunch of larger games in my steam library all left at about 8 or 10 hours, cos that's like a week of playing every night, and the feeling of me wasting my life is creeping in and putting a downer on everything. I'd like to play stuff like Nier Automata and Dark Souls but just feel like I shouldn't put time into those things. Maybe I should watch some letsplays like wot is hip these days.
I feel the same way. After about age 22 or so, playing games felt like a huge waste of my life, which makes no sense because I waste my time in many other ways that are less enjoyable. I used to think any game whose campaign was less than 10 hours was a waste of money. Now I actually prefer games that I can beat in just a few sittings. However, I have yet to find an indie game that I enjoy; I've regretted buying every one I have.
I also hate the learning curve of every game now. I don't want to read fifteen tutorials about all the different mechanics or character attributes that I'll forget if I don't play for a week or two. If the game isn't intuitive enough to pick up and play and figure out as I go, I'm not interested. This is prevalent in games across platforms, but seems especially so in PC games. I can't stand any more survival games with crafting.
I switched to PC about four years ago (although I played a combo of console and PC in the 90s and early 2000s), but I play quite a bit less on it because it feels like more of a chore to sit up straight at a keyboard and mouse, especially in single player games for some reason. I typically just play the same three or four multiplayer games on PC. I hate that I've been dumbed down to playing 5-15 minute matches of FPS instead of getting involved in a great single player. The last great single player games I got sucked into were Deus Ex: HR and Metroid: Other M (the story is an abomination, but I actually really enjoyed the gameplay).
Also, there's little need to upgrade GPU every year. I've started on a GTX 760 2GB in 2013, and I'm still using it. I just turn settings down if necessary.
