You do not have to play for 50 hours to know if you're enjoying a game
I didn't say I did. I said
I never understood this sentiment. Some times you need dozens or hundreds of hours - especially in a GSG or a Stellaris-type game - just to finish one game, or to figure out how everything works. It takes that long just to find out how the game works. You're not even qualified to say if Stellaris is a good game or not for probably 50 hours.
I think it's a difference in priority when critiquing something. When I wrote that I wasn't trying to (and I'm still not really) trying to do some real in depth analysis of stellaris and how "good it is" my priority is, was it worth the money I spent, can I recommend it to people? The money for time spent thing is why the hours are important. If a game has a good 50 hours but then gets boring, but it's five bucks, even if after playing 300 hours you could say it's a technically bad game I don't think that'd be fair to it. It would be certainly worth the money spent... Which sorta makes it a good game? Despite the reservations about it? Maybe? That at least seems like a reasonable thought to me. Stellaris I'm not totally sure on that front. I spent 40ish bucks on it and got 71 hours. That's a pretty fair ratio to me. Sure, only about 20 of those hours were really good. And maybe another 20 enjoyable. And the last thirty were a bit sourer, but they were at least worth my time (otherwise I wouldn't have put them in) so can I really say it failed in it's ultimate objective of entertaining me for an amount of time relative to the money I spent on it? From that perspective even if I think it has many many failings can I call it bad? Maybe from a critical stand point if I was trying to be a critic. But I'm not, I'm just thinking about if I could recommend it.
I agree with most of what you said here actually, except this part specifically
And the last thirty were a bit sourer, but they were at least worth my time (otherwise I wouldn't have put them in)
This is 100% observably false - and I'm not talking about you personally, but ALL THE TIME you see people sucked into things they actually don't enjoy, either out of habit, or compulsion, and generally when they aren't critically thinking that much about what they actually enjoy.
But again, if we go back to the first thing you said:
I think it's a difference in priority when critiquing something.
That's really the main point, I agree. If you're mostly worried about "Am I constantly having fun while playing this game?" then you can set yourself whatever introductory time necessary before you start checking, and then keep checking that. But if you're interested in something else, then you may not know if the game fits your criteria for dozens or hundreds of hours.
It took me about 300 hours of EU4 to decide I didn't like the game. I still play it occasionally to check on new content, but overall I gave it a negative review on Steam for any number of reasons that aren't "I'm not constantly having fun while playing this game."
