Comparing Construct with a hammer seems wrong for me too. It is a much more complex tool and of course c3 is a newer and better tool. So imo it is absolutely fine to give it a price tag. But subscription feels so wrong for a tool like C3 for me, I mean PS is a tool made for professionals - it is hard to learn and even harder to master and once you master it it is a powerful beast that gets major updates on a regular bases.
C3 on the other hand is so easy you can tell a child how it works. It is powerful and hard to master no doubt. But it could get so much more attention in the growing game designer community if it was more affordable.
And there are business models aside from subscription that rule the whole industry. It is not like we don't understand anything about business - I think construct could grow far beyond what it is now - a prototype creator for some small studios - into something really big if it wasn't so expensive.
And of course, a gym subscription or a sports club membership costs more, but how can I tell this to someone who starts in Game Design? "Well there are those free tools you might learn or this easy to learn tool, which is really great but it only costs as much as your gym subscription, but it brings regularly updates and new features..."
Speaking of new features, imo for the price the progress is much to slow. Since the start of C3 there are like 4 or 5 new features I recognized when I used C3 for a month. And some of them were possible with mods before. Of course these features are a lot of work and there are more improvements I didn't recognize but for the price I can buy a new piece of software every year.
