27 cents a day
I hate subscriptions because of the commitment. If I want to take a break from using Construct 3, then I have to decide whether to cancel my subscription or keep paying for something I won't be using for another year or two. (Yes, I'm to that point in my life where I measure activities and commitments in years.)
On the other hand, I love that a subscription finances further development on a product I love. From what I've seen so far, I'm definitely subscribing to Construct 3 as soon as it is open for subscriptions. If I decide to to take a break, I'll have to swallow hard and cancel my subscription.
