Talking about Amiga games that could've been Arcade games, one that stroke in my mind was Battle Squadron.
When I first saw this game on Amiga, I was SURE it was an arcade game. It took me some time to realize that was an original Amiga game.
And about Rock 'n' Roll Racing, can't understand why Blizzard took away the amiga and only developed for PC and consoles after The Lost Vikings. They could have ported Rock 'n' Roll Racing, Lost Vikings 2, Blackthorne, Warcraft .....
