I still think Construct 2/3 are pretty great. It was a hard decision for me to come and play with blocks. But still, Constuct 2/3 are just springboard into more serious game development. It shows you all the basic mechanic behind the games, while leaving out specific skill requirement in programming, so integrating into for example Unity would be much simpler. Were you already know how stuff should work, and only thing is to improve your programming. For me it still goes like this.
Gamemaker -> unity/unreal/monogames or some other professional engine.
Construct2 -> ^
Godot -> ^
Jumping from Construct 2 to Gamemaker/fusion, etc, after a year or two, seems to be bad progression.
Well, you can use Construct 2 or other similar engine, you should know that you must build your projects around pros and cons of Game engine! And should not hope for some serious improvements.
But I still I agree that Construct 2 and all other game engines should have the option to use almost entire engine freely with some neat limitations. When I was choosing which game engine to go with and Construct 2 had been yearly payment ~100 I would had hard decision, if there was no way to try it out for months with some small limitations. Picking Construct 2 is already like going to play Minecraft, while the game is wonderful and super cool, you still feel like playing with kids or are The Kid.
As already Construct 2 user the 50/100 year deal is super nice, complying and cheap. But when I think about back in time, when I picked the game engine as hobby tool, would I pick it again? It would be much, much harder decision than one time payment ~75. As when people go Construct 2 -> unity. Then there aren't potential clients who will come into construct 2, like engine X -> construct 2. Where engine X is free and then to pay a little extra and intergate into C2, as it is almost already the lowest tier.
I think limitations like: only 1-3 layout, 1 event sheet, fixed viewport/layout size, no groups, layers 1-3 max, some sprite limitation etc. Would serve newcomers much better. Then max 25/50 events.
Or old timers can pay 50-100 to unlock C3 with some limitation to develop their hobby projects. And then they can buy extras 25-50. - each unlock certain c3 limitations. Or pay 3-5 year in 1 go, to unlock it so called"forever" as people and their taste are different. There should be something for everyone.
