yea blender is confusing.....very confusing, um theres is one called 3d game studio, very very cool i might add, you can make 3d games to show off on the site or buy a commercial license to sell them, it includes a 3d model editor and then the main program where you put it all together, models, levels, and the programming to creat a game. it has a 30 day trial which aint bad, you should try it out =)
p.s. just do a search for 3d game studio..... i forget the link
