Perhaps the biggest change to Zelda 2 was the inclusion of an EXP system, similar to other Japanese RPG’s of the time. I think any kind of stats appearing in a Zelda game immediately got lot of fans backs up, though its hardly the most tactical system ever used, simply Life, Magic and Sword. The key to the game is the SKIP function, allowing to skip an upgrade in favour of storing the EXP for more expensive upgrades. This allows you to upgrade the sword earlier which is essential. As a kid I literally had no idea what these stats meant. No wonder I never managed to complete this!
