Here's my vision of the ultimate RPG. When you'd lock onto an enemy, you would fight in the vein of Soul Calibur. The A,B,X & Y or whatever would work as attack 1, attack 2, kick, and block. You would learn abilities from weapons, and armor. Fighters would learn combos, while mages would learn magic attacks cast in a more Streat Fighter way by assigning certain abilities to, say, quarter-circle back + attack 1, or back, forward + kick. Theives would learn the basic pick pocketing, lock picking, and other classic theif skills. You could upgrade to more complex classes much in a Final Fantasy Tactics kind of way, and they'd all have different abilities to learn. I'll just stop there, and leave the rest of combat, as well as story, social structure, and other aspects open for conversation. Please feal free to suggest an entirely different combat system. Just make sure you're more specific than "lots of characters" or "Good Story".
