Similar enough for me and if anything a bit faster to throw a prototype together with Godot. It does require a bit more knowledge, I agree. Doing scripting myself but the visual scripting looks to be similar to event sheets in alot of ways.
Gdevelop is garbage sadly. I appreciate the work the devs have put into it but it's just too buggy, too unstable to be usable. Needs to be rebuilt from the ground up which likely won't happen.
Like Superpower to but that's even less like construct I suppose.
To each there own. Use the tools that work for you and you feel you can afford. I just can't justify a $100 on what Construct 3 currently is.
Edit: It is a good setup for the business offering the sub but horrible for the game developer. I know at least half a dozen devs who sub to Unity for over a year and still have yet to release anything. Win for unity, costly for the customer.
