To be fair, the quality has been slipping quiet a bit lately. However they have Asia market that off balances that franchise and are super cheaply made with the same engine basically every time.
While the production values are the same as they were in the PS2 era, I don't think it's really fair to say they're worse games. The market for mecha shows is smaller and without biggest production values, you'll only get diehard fans getting into it.
