I hope more people make tools like this to save time for other game developers. I don't mind spending money on tools that will free up my time for other aspects of game development that there are no tools for and I have to custom make (believe me, there's enough scripting work to keep me entertained).
The complaints are prob pretty discouraging for these developers. Some of you want to make an income without spending years working on a game and this is a great way to have a source of income and still be a part of game development or a supplement to get you by until your game is done.
We NEED these tools! And we NEED people to develop tools like these. If they can earn some money off of it, it will encourage them to develop their product even further or develop something else that will benefit the community.
Perhaps more people don't make tools, because they can't afford to give everything away when they need an income source to purchase software upgrades so they can programme with the latest and greatest tools to create these apps. Let people earn something for their hard efforts. Some don't mind giving things away, others can't afford to, others want to start a business doing things like this. It's gotta be a real discouragement for them to read posts where people constantly complain ... I'm sure for some, it's not worth the hassle.
