I ask because I see many successful commercial examples with Torque 2D on Steam, but in most cases it's not only result of using constructor itself, but also huge ammount of coding (include replacing some parts of engine source code).
And as I see all other so called "constructors" don't allow do anyting serious withous learning their script language (like GM). And, btw, this language always can be used only in theis constructors. In this situation I prefer use C# + XNA and not waste my time with such type of "game makers".
I really hope Srirra's Construct-2 will be exception to this rule and I will be happy to buy and use it for my indie projects.
