Taking medication should be yours but for other actual adults, i don't think there is any specific gaming for adults unless you're on about something else?

I believe most people if not every person that works full time jobs have time to play videogames, if you don't have that much money then i'd always recommend buying a PS5 or xbox x considering they are max £550 for PS5 and £450 for xbox X, for PCs, you'll be spending double if not more than double that amount for a gaming PC.
