Let it not be said that both arcade and console exclusive beat ’em ups can’t be difficult (and aggravating) in their own ways!
Representing an arcade-first mindset is Capcom’s Knights of the Round: Another medieval fantasy romp that follows quickly on the heels of The King of Dragons. It even features a lot of the same mechanics, but is much more focused on a sort of version of Arthurian legend.
Representing the console-first mindset is Konami’s TMNT 3: The Manhattan Project. For once it’s a TMNT beat ’em up that’s not based on any arcade property, but is instead its own unique creation! It has a lot of refinements over the previous TMNT console games, but boy you’re going to be playing this for a long time in order to get a clear!
