Humble Weekly Sale: SEGA! - Giveaway creation

You can't split the key up therefore you cannot create a giveaway for just one game. :3

You could make it for one of the games and write in the description that people will get the others as a bonus.

Alternatively, write a ticket to Steamgifts and see if they will add the whole thing to the giveaway list for you. They may be some time in answering as they are often very busy.

thx, I will write them. Maybe it is not problem for only me.
