Using the XML API v2 I could build a list of languages for each game at each publisher. This information might not accurately reflect the actual offerings but should still give a decent hint. That information could be shown on:
- Printable games list: between publisher name and booth id
- Printable booth list: after game name or perhaps at the start of the notes field
Perhaps users should be able to filter the languages to those they understand or the list might get a bit long...
