Does anyone know of any free game developing tools?

To do what? There''s lots of stuff involved in ''game development,'' you should be more specific.

To make tile maps,3d software,sprite editing.

I don''t know about tile maps (you normally write your own map editor, since there is no ''standard'' format for tile maps). Blender is a free 3D modeling program, Milkshape is about $20, there are more cheap/free ones but I can''t remember them. For sprite editing just use any art program (you can try the GIMP, if you''d like, or get a much more simple art program). There was an article here somewhat recently giving lots of cheap and free programs, maybe you should try to find it ?
