To you it wasn't but for a lot of people it was. It took huge risks and it's graphics where superb. It actually looks great to this day. I've never called this game a filler, it just a huge letdown for me.
The original guy I quoted called it filler. I really don't have a problem with anything you said. While I have your attention though what huge risks do you think Sunshine took (besides its visuals)? It was Mario 64 with jet packs. And of the risks you think it takes, how do you think they're riskier than what 3d World is doing with multiplayer and such.
