Could you recommend me good mecha games?

I don't know if Transformers: Devastation counts as a mecha game but it do have giant robots with Bayonetta-style combat.

Nobody ever mentioned Kikaioh/Tech Romancer? You guys suck.

Also in the same vein, Gundam: The Battle Master 1 & 2 and Gundam: Battle Assault 2 (yes, they're different games because Japan's TBM duology actually has a story)
