I really, really struggle to understand this thinking.
I see comments like this quite often, but I don't actually understand the logic in that. I understand not wanting every single game being as long as something like The Witcher 3 I guess if you want to vary experiences, but having a problem with a game being something like, let's say 30 or 40 hours, is really weird to me.
You say "not many of us have the time to sit for more than that", okay, but what does this mean exactly? Aren't you going to actually play something else after this? So you do have time to play more than 15 hours of a game, you just don't want to dedicate "too much "time to a specific game. It's really not a matter of "not having enough time", it's a matter of not being able to commit to a specific thing I think, either because you get bored quite quickly by games, or because you're part of the "hype" people who want to play every single new games that come out just to be there on time.
I don't say this to attack you, but I just read this super often and it doesn't make much sense in my opinion. I don't see why, if you really like a game (of course if it's boring that's another story), you would have a problem with it being a bit "long". I'd rather play fewer games but truly enjoy them and have great experiences, rather than playing a ton but forgettable things that I just rushed in 10 hours, just to move to the next thing right away over and over.
It sometimes feel like people want to play games just to be done with them.
