Not sustainable? Bill Gates and Steve Ballmer made their money before all this rental ******** and they are worth about $160,000,000,000 And that's just the top 2 guys.
Correct. And how many versions of Windows and DOS have we had to purchase? I started on PC's with DOS 3.0. The MS guys also had something that Scirra doesn't, a virtual monopoly on OS's that started with IBM. Scirra is facing a market saturated with programming IDE's.
The problem with the one-off model in a saturated market is that you have to WAIT for someone to WANT your product in order to make money off of it. In my occupation it's called the "break-fix" model. I have to wait for you to break it before I can fix it and charge you gobs of money doing so. The HUGE problem with that is, I never know if I'm going to be able to feed my self next week because I have no steady, consistent income. IF you have a monopoly on your product and do great marketing like DOS and Windows then yea, you'll make gobs of money just like they did. IF you're in a competitive market and you product or service isn't the only one out there, you have no idea if your business will be open next week or if you'll be sleeping in the gutter. That's ESPECIALLY true if you're a small indy company working in a garage (gee, I think Bill and Steve did that) with no financial backing.
I for one have no problem with the subscription model. Ashley and Tom gain the confidence that their business is stable enough that they can hire more employees to give an even better product and even better service.
A few years ago when I first purchased C2, you rarely saw any Scirra member on the forum. I'd post an issue and never get an official response. Now? I see them on here daily solving problems for their customers. THAT's the difference I'm willing to invest in.
