While I'm happy like everyone else with the heavy release of the May version, I find it disappointing to remove the old UI System. Why force developers to buy Flash when UDK is a free engine? Why can't we have both systems available? Teams who wish to have the fancy UI stuff running on their games, they can buy Flash and get on with it. Other teams who are not really interested can use the old UI system for FREE. I believe that freedom of choice should be there.
So, do you really agree with removing it?
