Final fantasy for the cell phone is the PERFECT idea..... FFIII / FF6 jap was THE best rpg i'v played on the console , the gameplay was innovative ,the story was original , the characters had depth and it was LONG .... Most cell phone will have no trouble with the 2d graphics , and the game itself will only be like 5 megs .
Cell phones need more RPG's ... tons of 2d rpgs for SNes and genesis will work fine in java , and most people in this generation either haven't played them or will love playing them again , Secret of mana 1-3 , Final fantasy , Chrono cross , tales of phantasia just to name a few.... Instead of wasting time making crappy games just re make great ones !
