Indeed, a lot of games are very demanding. I played more than 150 hours of _Rocket League _ to come to the conclusion that I just suck at it, and that it's not for me ;-)
I played the most excellent Witcher III for more than 320 hours, it was more than 2 years ago when I had more time. I don't regret any second of it. Since then, I played lots of indie games, and a lot of them can be "finished" within 20 to 25 hours.
I like to have a feeling of completion, that "I did it" moment.
One thing though that I tried and I don't play anymore: punishing rogue games where you have no savegame and tens of hours of gaming can be gone in a matter of seconds... Except for Dungeon of the Endless which was rogue but all games ended within 3 to 4 hours if you managed to go to the end.
Ah well, too little time, and always something interesting to read, whether it's on steemit or not!
