What is the best video game development software?

i am in multimedia design and i am trying to create a new platform/ fight game. much like soul calibur 4, but with my own little twists. Does any one know of a game developing program that will let me create the game i want?

This requires programming, not just design. You really need to learn how to program. You can start with Blender. It’s a free 3D modeling package that has a very nice integrated game engine. You can do some basic game interactions with a tile-based programming system. Eventually, though, you’ll need to program to make anything original and interesting.
