Was this really ready for release???

So, I loved this game. For a good month I really like it, but soon it really... REALLY died off. This game is so utterly repetitive and theres nothing more to do besides beat the campaign (in like 30 minutes) and race friends. Idk honestly, not sure that this game is really amazing. SO NOT WORTH 10$... this game really should be free!
