Mail Order Monsters was one of those games I had a blast playing as a kid. Pick your monster, select attributes and weapons, and battle to earn money for even more upgrades. Best of all, you could save your monster to disk and bring it to a friend house to challenge his monsters. This is arguably one of the best games on the Commodore 64.
Mail Order Monsters for the Commodore 64 was developed by Paul Reiche III, Evan Robinson, and Micky Robinson and published by Electronic Arts in 2012.
