definitly have to get cfc and motm but as for the other game, i would go with either last blade or KOF r-2, but thats just me if you like rpg style games then go with faselei, but i thought it was somewhat annoying.
I loved Faselei. took some time to get the hang of it...and managing your ammo and resources for battles. GREAT GAME. Biomotor Unitron is a decent RPG as well. CFC is apparently awesome. I couldn't get into it, but have a buddy who spent something like 40 hours on it.
