It's TheDeadYoshi who is posting and it's TheDeadYoshi who is therefore having issues with the game crashing. A brief glance at the PZ subreddit (and I've seen it in other platforms) confirms there are also other people having similar issues, hence why it can be considered relatively common by the person who is posting.
No one suggested this game is rubbish nor that the crashing issues is a huge problem for many players.
It takes no effort to put yourself on someone else's shoes and understand why this thread started. It doesn't cost you money to show some sympathy either.
This person simply wants to play with no crashes and therefore asks for help or an official response. I wonder where else would you suggest this person to share their frustration because they can't play the game properly. What's wrong with posting your (and some other people's) in-game issues in the forum? Seriously....
It's the air of entitlement behind it...
Even if it wasn't meant, it's certainly the way it reads to some people.
Had this discussion before - I read the OP like it was a paying customer who bought the wrong top from a supermarket... It's like people who expect some sort of personal response from a large company and stamping their feet when they don't get one.
I understand frustration, especially when you really want to play a game and you can't.
But there must be a time when you give up. It's not an answer that anyone wants but sometimes it's the
ONLY solution - especially if the game is crashing sooooo much.
How would you define common?
20 people? 50 people? Out of how many reviews on Steam? Because not everyone will review the game - the number of players is unknown therefore you can't say the relatively few people (hell, even if it's 200 people!) posting on Reddit have some sort of
common issue. Because I bet Frontier has sold way over 2000 units of this game, and thus 200 is just 10% - not very common. Plus, the root cause of the crashing isn't the same for everyone. But there seems to be a large suspect (although not sure that would affect the OP as surely underwater feeders wouldn't enact a game crash on start up?).
But put yourself in Frontier's shoes.
You get people who say the underwater feeders are crashing
their games. Then you get people who have underwater feeders working fine.
How do
you work out what's happening to those who have the crashes? Because logic says it isn't a problem with the underwater feeders as not everyone is suffering with crashes. So that points to something else on certain systems. Are all those systems AMD or Intel? What graphics card do they have? Ram? Windows version? It's hard to fault find when you haven't got a common theme.
Just like the other chap who has some sort of problem with the "path to destination" and the Quarantine building. Most of their posts are unhelpful to people trying to help (as they're just showing frustration) and the user appear not to take advice very well... stamping their feet, expecting Frontier to fix their specific problem with the game. A very isolated problem.
It's so hard to get the specifics of
why a game may crash and the limited support that can be given (IE sending in saved games) is exactly that - LIMITED. Your computer system is different to mine and is different to what Frontier will use. If they play the game and get no crash, where do they go from there? They've tested and it's not crashed for them, so no fault found. Unless everyone has exactly the same components, exactly the same version of Windows and exactly nothing installed but Steam and the single Planet Zoo game, it's pretty hard to figure out what might be causing issues.
Crashes are frustrating and rubbish but most are not easy fixes and every piece of software out there is likely to glitch at some point for someone, even constantly for some people.
I struggle to emphasise as people make mountains out of mole hills these days.
I do hope this at least gets fixed, because as much as I'm "okay" with the routine of having to start up the game, watch it crash and then actually start it; I would love for it to be over.
