I would be elated if they were to release all 3 GBA games at once, stateside shortly after the completion and release of Mother 3. I know we never got the first 2 GBA offerings, but I would not hesitate to buy all 3 if they were to be released here all at once. I would even hold off on playing through 3 and play through them in order.
Even if it isn't released here, I'm sure a translated ROM patch would be created by absolutely RABID fans who awaited it's release.
Yeah, I'd rather they keep the 'Earthbound' name, since it's what we started the series here as. Comparing the names 'Earthbound' and 'Mother' right now, of course I'm going to choose 'Earthbound', it's what I'm used to and know the series as. But I could easily have said 'Mother' if that's what I knew it as. I wonder why they called it 'Mother' in the first place? 'Earthbound' makes sense, aliens and all that... >_>
