To give a simple example, the IV Generation Mecha · Dark Knight that Su Mo looked at before costs over 1 billion Star Coins, reaching 1.5 billion.
It's entirely possible to buy a Fake V Generation Mecha instead.
Judging from the performance parameters, a Fake V Generation Mecha for 1 billion Star Coins is indeed slightly better than the IV Generation Dark Knight.
However, it can't be compared that simply.
The difference between the two is like that between a high-end stripped-down version and a lower-level premium one, each having its own advantages and disadvantages.
For example, a 1 billion Fake V Generation Mecha simply can't be piloted for too long; over time, it wears down the driver.
But an IV Generation Dark Knight can fight for a long time, and if controlled well, can even challenge higher levels.
So normally, everyone would rather buy a high-end IV Generation Mecha than a low-end Fake V Generation Mecha.
