If I ever feel like this it’s usually just temporary boredom and I just take a little break and jump back in
I’ll tell you what really helped me keep my passion for gaming for so many years :
1. I alternate between games rather than try to complete one quickly this way I don’t burn myself out
2. Keep upto date with technology, buying an OLED tv and a good sound system was one of the best purchases I’ve made and made gaming so much more immersive .
3. Revisit old games , my examples halo series , half-life , mass effect , dead space
4. Have other hobbies and interests , mine are drones , hifi , music , photography, running , movies
5. Be mindful and try not to be too critical or pessimistic, try to Appreciate the small details and the amazing work and detail that goes into games (coming from a zx spectrum veteran ) , I have replayed uncharted 4 so many times and never get bored as the detail and immersion is stunning , the new halo update is also amazing and really tajes halo to new level of immersion .
