Working Designs was all about living the fanboi dream. If they did Radiant Silvergun, it would have had a stupidly flashy cover with lots of glittery pink on it, the voice dubbing would have been laughable, it would have contained references to Friends, Bad Boys, and Star Trek, and they would have altered the entire leveling up system like they did with Silhouette Mirage.

In contrast, GQD is just commissioning additional print runs of games from the companies. It's extremely unlikely that they'll acquire a license to distribute a game not released in the US in the first place, translate it, and then distribute it.
