Frame Gride, but each kingdom faction had its own variety of mechas. You have a mass produced mechs like the one in front mission, limited and grounded in mobility but excels in numbers since it is more manage-able to produce.
You have mechas like gundam who can fly at high speed and can do beam spam, a higher tier more advanced than the front mission mechas ones.
Then there's the even more advanced ones, mechas that literally a super robot tier that either comes from ancient civilizations or an aliens with their even more advanced technologies.

It plays like Saturn's gundam blue destiny.
