I put the interesting the guy said here :
He's right , lot of people like me would only want solutions with great workflow.

Well if you are like alot of us(well those old enough) you have a job, and that job takes 70% of you r time, then if you like even fewer of us, that writes programs all day long for a living, then the last thing you want to do is write a engine, I am so sick of people messaging me and saying, hey I am writing my own mmorpg engine, wanna help? Heck no! Why would I waste my time? So by the time i finish it, the graphics will be out of date? Or someone else will come along and make one exactly like it faster? Making a good game does not require you having to write the engine also, but it does require some coding. I think makers are the greatest. makes it easy for those of us that program so much we get sick of it. I write at least 2000 lines a code a day at work. The last thing I wanna do is deal with a dang engine for a game. Just my opinion though. I give props to anyone writing their own engine. *poke *poke

The guy is right , In fact each of us depending on it's game style would need
the appropriate editor with all tools in it, ready to go.

I find Torque game Builder for XNA , this sort of very powerfull , very easy tool , ready to produce any type of 2D game you want without coding (only behaviour)
