I've made command line tools for the most part for Super Robot Wars A Portable, not because I can't do GUI, but because a GUI costs a ton more time. It would be great to have an efficient GUI framework available. I haven't found any.
Having said that, I'm currently coding a GUI to edit the story of that game, just to ease translators's lives. (I recognize that translators have more work on that game than programmers - probably 2.5 times as much. But the next person to call me non-altruistic gets a wall.
Seriously, after spending 2 years on a game, you don't really want to play it anymore. The joy and fun is in being with the team and doing stuff you've never done before.)
I'm wondering if this could be something to share - I mean, designing a story editor in a generic way, is it feasible or useful?
'cause I'm more about better sharing our resources.
The bottleneck on Japanese-to-English translations is still the availability of translators.
