Multimedia Fusion is the perfect tool for creating applications, multimedia applications and exciting games. MMF continues the amazingly powerful graphical programming interface started with Klik & Play and continued with The Games Factory. Powerful new objects, exciting new transitions and a graphics library packed with megabytes of royalty free graphics and sounds. We also offer an SDK package so you can make your own extensions using C++ and plug them into MMF.
I have used this for a long time, and I can't use anything else :)
Most easiest software to use!
