A remake of King of Dragons, or even better Knights of the Round with its armor system improved (like, the less damage you’ll take, the earlier your armor will upgrade) I had this idea when I played a Pierwolf game based from King of Dragons. Another: a long and solid action RPG based on Magic Sword (always from Capcom): with many levels outside the tower as well, varied settings, villages to visit and NPCs to talk to, no maps to travel, but all directly on game like a good old Wonder Boy or Faxanadu. The tiny sprites and backgrounds of Magic Sword make it easy to use graphics from other games, especially from Capcom itself (Tiger Road, or everything from Black Tiger: backgrounds, enemies, player, weapons...)
