There’s a full page for the UNDERTALE 10th Anniversary Stream, but there isn’t and never was one for the 6th anniversary stream, even though it also had differences.
It was nowhere near as big as the sweepstakes nor the most recent event, but I still think it’d be good to catalogue.
On a separate topic, a better summary of the Sweepstakes stream would be good. Right now it’s quite lacking… compare it to the Valentines day gag which has a summary of the whole thing in detail.
I’ve recreated all the unique stream assets already, actually, I’d be happy to put the rest of them up.
