I'm employed in the gaming industry as a Graphic Designer (currently online casino gaming), and have been working at AAA studios, and indie studios in the past.
I have been using C2 on and off for about 3 years, doing my spare time projects for fun, but aiming to release my own games eventually. As a non coder Construct 2 was my perfect tool since I don't have any interest whatsoever in learning any coding language. I feel dyslectic or an anaphabet when looking at regular code syntax, but the Event sheet I can comprehend very easily.
I've tried a plethora of different engines but many of them required code or used some weird state-machine coding which I didn't like either. My main reason for choosing Scirra's product is the Event Sheet. I have failed miserably in the past producing anything even remotely resembling a game in other engines but C2 allows me to take my ideas from paper to actually, interactive games.
I'm using C2 in my spare time for my own projects at my own pace learning as I go, but aiming to release my own professional looking games with it.
I will be subscribing since I like C2, i think C3 looks promising.
Subscription/Web based/Html5/Performance/native or non native -- None of those are any issues to me. As long as they keep the Event sheet and and keep improving by time I'm a happy camper. Without C2 (or the event sheet) I wouldn't be making any games at all probably.
