A new adventure game has been released in the series and it's named Final Fantasy I & II - Dawn Of Souls. The game is much simpler than its predecessor, and it features a lot of new weapons, items, and armor. However, it still feels challenging, and many gamers might not enjoy it as much as the original. This is why I'm not giving this game my full recommendation.
While Final Fantasy I & II - Dawn Of Souls is a remake of the original Famicom game, it does add extra content and tweaks the gameplay. Its difficulty level is lower than its predecessors, which is a plus. You can no longer lose your stats after dying a certain number of times in Final Fantasy II, which was a common issue in its first release.
