Do I need to delete this GA? Help please

I thank everybody in advance for the answer, and especially the member who approached me to tell me I might need to delete my GA. I just want to understand if this is really an issue, so I'm only seeking a confirmation

Seeing as how, as you point out, both packages activate the same stuff on Steam, I see no reason why anyone would think they weren't activated so everything should be fine. (In fact, I'm pretty sure there is no way to check which of the two packages was activated at all, since I doubt the Steam API gives that info.)

Since it is a giveaway for a group Agree to delete this giveaway if key not working I'd write a support ticket and wait for their answer. In a worst case scenario you will just delete the giveaway and redo it later.

So I will re-formulate the question I guess, on the example of Twin Sector: when I select to create giveaway for it, steamgifts tells me I'm creating GA for ID 27900. My key is for Twin Sector retail though, subID 1910, but when I click on apps (that are included in the subID), it links me back to 27900, so I just assume that's okay, and that the subID of the product code does not matter as much as the app IDs of the contents/apps

Correct or wrong?

I wouldn't worry. First, it's for the group Agree to delete this giveaway if key not working, so it's almost sure that if you ask, they will agree to delete. Second, and in this case more important, the winner in this particular case won't be able to know if it's one or the other, since they both activate the same.

I'm pretty sure you don't have to delete it since they are the same thing. You should probably just check the winner if they have the game already. But if you want to be sure just ask a mod (probably one will find this thread by themself) rather than create a ticket.

I am not 100% positive, so hopefully someone with more knowledge will clarify, but I don't think SG can see what pack of games someone activated, it just knows what games are in the pack being given away and then checks to make sure those individual games are activated on the account.

If there is a key that activates 2 games and another key that activates those same 2 and more, you should be able to create a giveaway for the 2 game pack but give them the key that activates more games because all SG cares about is that they have the 2 games from that pack on their account. I believe you could also give away a bundle that includes multiple games and then provide the winner with multiple individual game keys as long as you provide them with all the games that are included in the bundle.

Edit:
Example: I believe you could create a giveaway for this bundle and then provide the winner with 5 individual keys. Or you could create a giveaway for one of those games and give them a key for the complete bundle, but you would only get credit on SG for the one game you selected. It should be fine as long as they activate the games included in what you create the giveaway for.

This is what I believe to be true, but I could be wrong.
