I have just finished playing this game on my emulator.
I loved it.
The reason I started playing is because my favorite character to use in Super Smash Brothers Brawl is Lucas.
(Technically I play as Claus, since I only ever use the red-headed Lucas, but he is still called Lucas in game)
I wanted to know their story. So I found a Mother 3 rom online, downloaded it, and played.
It's suuuuch a cute, silly, sad, happy game. I highly suggest it if you like simple RPGs.♥
