The mobile version updates the blitz and Cyans swdtechs to work better.
I think if I wait till the modders fix the sprites it would be one of the best but again it would only be fixed up to the gba version bugs wise.
Brave new world looked so good but it adds some things to the plot that I disagree with (Narche speaks like canadians, red bulls an item and a bunch more dialog that wasn't in the original game)
I wish I knew a sprite artist that could finish work on it akin to this mock up http://i.imgur.com/bs1q9Si.jpg
I was hoping for a more faithful to the original japanese script translation patch but as far as I can see most patches try to stay faithful to the woosley script... Fans of ff6 just don't think the way I do I guess.
