It's these kinds of attempts at pedantry that get in the way of discussion.
To invest time is to spend time whether playing or working. You're attempting to make a disctinction with no material difference.
He absolutely is not, at best you dont understand what he is saying. Investing time means you do something now in the hopes of a future payoff. That is not pedantry, that is how many people genuinely play. That is why people want to know the future of a game; many literally say they will stop playing if they dont like the future plans. In other words, they dont have enough fun
now, and they invest their time playing hoping it pays off in the
future. And that absolute is a completely insane way to spend your free time. Playing a game should be fun
now. There absolutely
should be instant gratification. Having people have fun is the sole reason for entertainment products to exist in the first place.
If you 'invest time' in the hopes you may one day have fun with a computer game, you should stop
right now. The very concept of 'grinding' exists solely because people voluntarily 'invest' their free time because they somehow cannot imagine they could do something that is fun now and rather spend their time doing something they readily admit is not fun at all.
The very concept of 'investing time' is a rotten festering wound in contemporary gaming culture, and rather than it 'getting in the way of discussion' it should be discussed openly
far more often.
