i would rather go for

than the Orphan thread

Are Wii keys even redeemable anymore?

I think you can make a giveaway in a thread for them?
I didn't know humble ever really sold 3DS games 😮
Now I'm quit curious to know what games it are 😅

I'd suggest to give away keys in this thread: https://www.steamgifts.com/discussion/tnWVh/anti-ninjas-key-drops-no-keys-in-messages-though
Of course it's more tedium compared to throwing keys in the shark tank but on the other hand you avoid bots and there's a higher probability keys are picked up by people who appreciate them
