Lots of these kinds of games have reached their sales by selling at a very slow and steady pace over a long period of time, and a sequel would look to have poor sales against the original even if it was selling better until it had been on the market for years ...
Beyond that, there is an element of saturation in the market. Very few genres can support more than (about) 5 games in a year that sell particularly well. If publishers choose to release 20 games in a genre in a year people should expect the majority of them to have poor sales.
