I've submitted my game Star Story just to see how things work out. I did notice some game had a broken image for a thumbnail, and sometimes I had a bit of trouble closing a window with the details of a game. Oh, and perhaps "science fiction" and "fantasy" could also be nice tags.
Now I did add the "Other Language" tag as Star Story can be played in both English and Dutch, as per recommendation, but I am a bit conflicted about this, as it can work a bit confusing, as people may think the game's not in English (which it is, but Dutch is merely possible as well). Perhaps having a separate field for languages in which the most common languages are listed with "other" when a language that is not (yet) listed is available in the game as well.
Just a suggestion.

Ah, I already thought the broken image games had no thumbnail in their submission. Perhaps a default icon for games without any images is a good idea. And yeah "bilingual" or "multilingual" might cover games in multiple language better. (My game House of Cards covers English, Dutch, French AND German, which is four languages, and yeah, I may submit it soon).
