I've got interesting bug. If Publisher or Developer's name contains only numbers, RCB didn't show game listing.
xbmc.log contains:

12:27:35 T:3464 ERROR: EXCEPTION: argument "label" for method "XBMCAddon::xbmcgui::ListItem" must be unicode or str

I've changed fields manually in NFO files and it helped.
