Not yet. Depending on how many Sunless Sea keys there are, it's possible, but for others where you have a single copy, or just a few, only if they're still there with a few days left maybe. And doubt they will be, see requests right away.
Speaking of requests, seems like a few (more) people discovered the candy store recently and want to see how many jars they can stick their fingers in... In case of keys that don't expire soon, may do with a single exception rule, as in can get one daggered game in addition to a non-daggered one, or just a daggered one if you wouldn't otherwise be eligible for a non-daggered one, per month. If the others are not desired by others, you can ask for another next month.
Don't worry, I am not requesting to have these games. I was more curious if these keys are going to be dumped even though none will make to get it or they will get dagger symbol before the time comes. But as I see you answered my question. Probably zeogold thinks likewise you.
