Typically if you have a commercial game and it is doing well you don't want to tell people it was made with a game creation/scripting/programming app, for some reason if it isn't written in C++ people don't consider it worthy. Some good games you might not have spotted on the site though:
Tito the Bouncing Alien,
Hijacker
Star Wraith(1,2,3,4,)
Riftspace
Miss Kitty Fantastico
