Let me answer from personal experience. When i started university (which was about 3 months ago) i was planning on taking my xbox with me. I decided against it because there was no display to use. A room mate bought a TV with him but it was tiny and didn’t have a HDMI plug. Long story short i simply don’t have the necessary hardware since i don’t want to carry my massive TV 160 km on a bus. In future i will get my PC and use a swapping system based on what i am doing in the moment to game on my PC and Xbox, but as of right now i lack the hardware.
Most adults also stop gaming due to lack of time and i am sure that i will too at some point. Uni exercises are easy now but i guarantee they will pick up at some point and i will struggle to keep up. But as of right now, i have way too much time on my hands.
