Plenty of time? Please. The day is ridiculously short with far too much to do. The fundamental issue here is games preventing one from engaging life at a higher level.
There's a serious disconnect here between people and sometimes even society though. What constitutes "engaging life at a higher level"? It's unlikely everyone would define that the same way, and in some cases it's even more context sensitive. Let me give some examples:
- Person plays games instead of finding a significant other and getting married when he otherwise would have. Most of society would agree that games were a detriment to this person's life.
- Now, take a different person...the kind of person who would never marry regardless and knows it. Just to make it less debateable, let's say this person picked up gaming at 40 years old and never looked back, and hadn't seriously dated anybody for 10 years prior. This probably isn't the games influencing his decision, but society might see it that way.
- This one is more personal: Games, or going out drinking at a club with friends? Man, have I caught flak for choosing the former. But I'll tell you what; the latter is an *actively unpleasant* experience for me. It's not really logical to blame game addiction for an aversion to being unable to hear the person next to you, breathing in smoky air, and worrying about who's actually going to transport people home alive safely. On the flip side, given the option between video games and flag football in college for example, I always chose the latter. I still heard clamoring that I was somehow video game addicted (more so by parents or the clubbing friends, and not anybody else haha), but never flag football addicted, work out addicted, or just going to bed rather than deliberately suffering addicted

.
This brings me to an interesting point: what is your next best alternative to playing games from an enjoyment perspective? To me, the big indicator here is if that alternative is something that one could logically frame as more desirable, or something that should be, with a healthy dose of skepticism in terms of opinions and whatnot. There is a big difference for example when one's family wants to do something nice (dinner, family night, going somewhere everyone wants to go) vs "you're ignoring us and playing games but if you were watching tv with us instead or doing nothing we'd have no problem whatsoever". The former can be a legit gripe depending on context, the latter isn't. At all.
It comes down to whether the hobby is dominating time that the person himself would otherwise wish to allocate more evenly, but can't do so due to addiction without realizing it. As I've picked up other things in life I do play considerably less as a result, but it's still easily my highest preferred down-time choice.
