Well it is the only program that can make a *.SWF file extension. Which is the only game format that armor games allows. There are others out there that are free. Try looking at the programming stickies.
Why did you make two of these? One here and in Programming.
But yeah, I don't have a clue what to use besides Flash and whatever Actionscript is o_o I do think there are other programs, not sure if they are any good, never really Googled anything on it lol.
