Tutorial Description - Well first off, since we are developing these games in Flash, I'd highly suggest having either Flash MX or Flash MX 2004. I still only have Flash MX but it's perfectly acceptable as a form of game creation.
Then comes the side resources. If you want sparkling good graphics and awesome tones, then I'd suggest grabbing a high quality graphic design program such as Adobe Photoshop. There are other products that will work just fine such as 3D Studio Max for adding a 3-dimensional feel to the game
