Final Fight amiga is okayish on the code side, what it lacks is recoloring. i noticed that each or most usgold games lacked mostly in the graphic department.
Compare with a game like snow bros or Pang, ok, those are simpler, but the graphists made their best to "dress" the games. final fight with an amiga palette made by a good graphist would have made players more "conciliant" with the result.
But yes as a code program wrote from scratch in 6 months, it's nicely done. And i also myself acknowledge for the Double dragon 2 effort. The game is very good !
