Less RAM has been the biggest issue, especially on XBox Series S. We have reduced memory usage of many different systems. Art is now getting optimization attention to use less memory.
This time around, the console version is sharing the same project files as PC/Mac/Linux, so it is all the same, except for occasional checks in code for required differences. A good example is file system access. PS5 and XBox each have different systems and rules to read/write files than PC/Mac/Linux.
The gyrocopter has a new model with a passenger seat that I will be replacing the old model with, when I get to it. It will still fly the same, as it is a gryocopter, not helicopter. If we add a helicopter some day, that would fly like a helicopter.
