The development of mysterious seas was going smoothly.
The development process for Triple-A games was relatively fixed. Many of the playstyles and systems could be reused for future games after they were made.
Just like how Naughty Dog was influenced by the last survivor (doomsday of the United States) when he was developing mysterious Seas 4, the two games had some similarities in gunfights and fighting.
On top of that, Chen Mo's art team was constantly collecting art resources, including scenes, characters, and so on.
There were a lot of art resources in the illusion game engine. Some of the high-quality ones could not be used immediately after purchase, but some modifications could reduce the workload.
You could also buy some art resources on foreign websites. You didn't have to build your own models and stickers for some special scenes.
