Lunar puts you into the role of Alex, A young man who grew up listening to stories about ancient heroes and adventures, who wants to go off and have his own adventures some day. Living in a sleepy little village, not much happens until one of your friends asks you to join him on an expedition to some nearby caves. The two go, and start a quest much larger then they had anticipated with Luna, a young singer from the village.

This title has all the makings of a great classic game, good music and effects, A compelling story with a deep plot, a fun combat system, and extra little bonuses that make you want to discover all that the game has to offer. The story itself is well written and fun, sometimes humorous, sometimes sad, you'll find yourself invested into the characters and you'll get that warm feeling when your hero does something big. You'll laugh, you'll cry, you'll want to keep fighting till the very end.

This is the original edition of the game. They later released "Lunar: Silver Star Story Complete" with even more content, re mastered music and graphics, and full voice acting. Both games are amazing. And I highly recommend this game if you're looking for a long game to invest your time into.

Difficulty 4) The game starts out with a lot of Hand holding, Nall, will frequently rush in and heal you if you get weak. Later in the game it gets more difficult, but it still stays a breeze to play though. 

A good start, but perhaps you want to tell us more about the game.
