Well, I don’t really know about any good free alternative.
The point is that, even free software need regular updates but you and 4ian just haven’t got time to update GDevelop regularly.
If it even possible what I’m saying it would have the benefit of using an engine that is updated regularly by paid developers and if it possible with the events to keep them as a collection of Tier1 code that can be edited, extended and created by anyone then you and 4ian need to do nothing but keep the IDE running and hopefully the community going to update the events so people know nothing about code can still use all the features.
It doesn’t have to be GDevelop, just keep GDevelop what it is and make this one a separated product and call it different, AGKDevelop maybe and make it free or charge money for it as you wish.
Of course some people might say there are better frameworks out there for free, but the point is, the frameworks require C++ and compilers and SDK’s and what not, AGK Tier1 require nothing but it own compiler and that’s the point. If you can manage somehow to generate Tier1 code and send it to the AGK Compiler or just open it in AGK and do it from there, it would solve all the problems and combine the power of the GDevelop IDE with the power and regular updates of AGK.
If it done right, nothing going to beat this marriage.
Yes, AGK cost money, but it is on sale all the time, you can get it for 50% less in every 3 months if you wait and it is nothing compared to what AGK has to offer:
-available for Windows, Linux, MacOS and the Pi
-Tier1 code (Basic) can be exported to Windows, Linux, HTML5 and Android without requiring any SDK’s, can also export to MacOS and iOS requiering xCode
-Tier1 code can be tested on any device through Wifi (absolutely love it)
-Tier2 (C++) can also be used in case you prefer but it is require messing with compilers and SDK’s as usual.
-packed with all features most user dreams about
Free or not, I just can’t see GDevelop going anywhere unless you and 4ian cooking something but if you don’t, this is the only way I can see GDevelop stay above the water in some form.
