Think of it this way. You have a bad game that you've made, and you know it's made. All of the development costs you've put into it are already sunk. Do you:
1) Cut your losses and release the game as is and recoup some sales from people who don't read reviews, etc.
2) Start over and completely revamp the game and risk it not even ending up any better on the hope that sales will increase a bit
3) Can it completely and don't even release it.
Usually #1 is the most profitable path unfortunately, with maybe a small amount of #2 for polishing/bug fixing if it's deemed worth it.
