I own a C2 license on which i'm working for a very specific project, a dialogue tool, so that C2 and C3 users can incorporate it in their own project.
However I definitely intend to get my subscription to Construct 3. There are more and more interesting features. Text effects, new debugger, new functions, new behaviors, Timelines... As someone said : It feels like a new software at every new features. That's worth a subscription.
