1 if you speak japanese 2 if you don't ![Look at me, I'm invisible! :P](http://zfgc.com/forum/Smileys/tplink/tongue.gif)
Well there's a fan translation of 1 right.
I guess what I'm asking is by starting on 2 will a miss a lot of the story or is the story not continuous.
The story is continuous. However, the US only got Earthbound, so the story was adapted (I believe, at least) in a way that wouldn't require Mother 1. In truth, the only continuous thing in there is Giygas (or Giegue) and the Starmen. That's it. Giygas is attacking 'again' in Mother 2.
I'd say, start with Mother 2. Mother 1 has, to quote some people from Starmen.net, "balancing issues at the end of the game". If you want to play Mother 1, I say grab the GBA fan-translation.
