Yeah, youre right with it, when you said, that most viewer want to see the "right" way. I think i didnt find even one blind LP with genocide first to get the different endscene in the good run. that would be interesting to see from someone who is really interested in the story. There were a lot streamer/YT who played it just for the views and didnt even understand the obvious stuff.

I just came back to check on jacks channel after not watching him for a good year. Just to re watch some of his old stuff and I see this video and I can’t stop smiling like an idiot. It’s nice to see that he hasn’t changed but grown as a person

Hey Jack, please, I am begging you, check out the Game Omori. It's a game in the style of Undertale but with it's own style and way of telling a story of love, hate, tears of joy and sadness, and so so much more. And don't just take my word for it. Just wanted to rally that thing to you. I hope it reaches you. Thanks for you hard work over the years

Play undertale genocide root cuz it counts a different game cuz the story is different

I always sorta imagined sans with a Patrick voice but more chill. Less... exaggerated, yknow? To fit with his more lazy and chill demeanor.

It's strange to see Undertale on this channel again...... bc the Undertale series was the reason why I started watching Jack and I'm not dissapointed xD Also I still love Undertale so much, even if I'm not too active in the fandom anymore. But thanks to that game I made many friends and even visited america for the first time for a small Undertale convention. Seeing my favourite US-firstr playing the game again that made a big, positive impact on my life.... that fills me with determination!

Jack: this game really is effected by your choices The one decision you get in the game:
im so rak and energy
i like how of course there are things he barely remembers, but there are also things he had the same reaction to despite it being 5 years ago..

Playing pacifist ending first makes you love all the characters so when you do genocide ending you feel depressed

This is random but: I think Jack should play Night in da WoOoOoOdS again XD It was one of my favourite series he did and I can't belive it's been so long. Mae the cat, Gregg the fox, Bea the crocodile and Angus the bear! His voices for the characters were beautiful

Comparing sans voice to Patrick star’s is making me compare all the characters to spongebob characters and it almost started freaking me out until I realised it was starting to become a little far fetched

Jack, I really didn't think UNDERTALE was for me for years. everything I heard about it, frankly not much, didn't really seem like i'd like it. Then I found your let's play in Winter 2019. U MADE ME FALL IN LOVE WITH THIS SILLY, STUPID, AMAZING GAME! THIS IS THE BEST GAME I'VE EVER PLAYED! THANK YOU FOR SHARING THIS WITH ME.

At 24:50 he asks where the third frog is... what i discovered in my play through is that if you kill one of the frogs in genocide run, no matter how many fresh saves you have, that frog is gone. Another great example of your actions having consequences
