Specifically, I think that something taking place between Mother 1 and 2, following Geigue/Giygas and his forces as they leave Earth after being defeated by Ninten. (You probably wouldn't play -as- him, as he'd be too powerful, but rather you would play as an abductee or perhaps a Starman.)
I'd try to make something fairly short like this, but RPGXP doesn't agree with my computer for some reason (it bluescreened on me at one point), nor do I have much experience with it - so I just thought I'd toss the idea out there for anyone who wanted to use it. Note that I haven't played M3 yet, so I'm not sure if this idea conflicts with anything... another reason why I haven't made anything. I'm waiting (and am quite excited for) the translation patch or an unlikely official release, whichever comes first.
