Sega's Altered Beast is a video game classic!  When it came out in the arcade system, people would gleefully dump coins into the system to play as one of two resurrected Roman centurions in hopes of beating the nefarious Neff in the underworld as they rescue Zeus's daughter Athena from peril.  Regrettably, those who had the original Sega Master System were likely sorely disappointed with the disjointed and disorganized gameplay that the title had on that platform.  The resolution?  Sega released it on Sega Genesis, where it played better than it did in the arcade (let alone Sega Master System) and allowed players the ability to customize the game's difficulty (there were control options that could enable a person to award or remove lives and health bars, in addition to setting the game difficulty.)
