LDW has said that they have plans to do a sequel to Fish Tycoon, but have made no announcements about when that might be. LDW's home page shows Fish Tycoon for Mac, Village Sim for Windows and Mac, as well as Plant Tycoon for Windows and Mac in their "Coming Soon" section. You can click on the Coming Soon link to see the progress of Village Sim for Windows (which is their next project), but we'll all just have to wait for them to tell us more about any other games!
