3run,
I don´t said that you´re not experienced (I know your stuff and it´s pretty amazing) and Dan hasn´t asked for a painting tool inside Gamestudio. It was just his response to superku´s point that Gamestudio is a complete solution.
It isn´t, because a complete solution needs a paint tool as well.
Don´t get me wrong, I love MED and I use it pretty often when I do Gamestudio stuff. But I can also understand Dan´s points.
[edit]
No. I mean, come on, it´s just another engine with lots of good and bad things.
If you´re heading for windows only theres no need to switch "ASAP".
