Most people I think to get by the 1g limit is storing the file externally and just add a down load link like drop box and mega.
Hey great tip!
I went hunting for a game to compare and I did see some games have integrated downloads listed as "External." I did not realize that was an option.
Edit - Also saw some have file sizes as high as 7.5GB, so either way I can keep working here.
Thanks!
