GameMaker: Studio

Hey everyone !
I just saw that steam now have a some software programs, and I just saw this really cool program
What do you think? im allready downloading it, should be really cool to have your own android game !
and btw, check out the "Studio Master Collection" ! 449$ after discount ! seems pretty expensive, I bet I wont see this pack here on SG ;)
Have a nice day everyone, im gonna make a game, and if it will be good enough - ill share it here !
Feel free to do so yourself :)
