So today's livestream is not just about me and the channel, it's about honoring my team, and honoring all the Theorists out there like you. Thank you.

    I always know how important Game Theory was to me, ever since I found it more than 9 years ago. But I had to admit I wasn't expecting to end up crying more than Matthew did in this video. This has really made me happy. I really look forward to some GTLives where they actually play more of this amazing game.

    It's odd. I used to really love GT. I even tried to learn the theme on violin at one point. But my interest in GT dwindled out sometime in late 2016; it was either the content of the times not interesting me enough or just growing up. & Yet I still routinely checked out what the channels were up to from time to time. I watched stream archives, waited in vain for DeadLock to return, & mourned over the loss of Ronnie "Oni" Edwards. I may not be as invested in the community as I used to be, but I am glad that I had those early GT memories & that the channels continue to provide such for others. Happy 10th, Matpat.

    Congratulations Mathew and Stephanie. This is a big milestone you hit. With all the hard work and love that you've put into all your channels, I'm sure they'll be around on one platform or another for many years to come. And I'll be here, watching them all. Love your videos and live streams (even the more cringe-inducing ones). And take care of those colds. It's not fun having to work when you're not feeling your best. So get as much rest as possible.

  • Le' Goat

    I think that Villagers are a religious group who cast out wanderers and Illagers who refused to follow their practice. 1. We know that the Villagers have Churches in most of their villages. The big stone tower building with fancy windows and torches. 2. We know that Villagers can build but never do, at least in front of the player. I call to attention exhibit A: There villages, it seems unlikely that the Masterbuilders built them and they have lasted for an untold amount of time. They'd at least need some repair from the occasional creeper. B: Notch said that he wanted to make Golems look like Villagers because "It's unlikely villagers would build anything that wouldn't look like them." C: The crafting table. They have a crafting table in their libraries, how do you think that could happen if they couldn't build and craft. D: The bookshelves, look at the bookshelves in the library. Those had to be crafted. E: We know the Illagers can. I sorta doubt the master builders created a replica evil mansion with carpet maps and bed and end portals. 3. All villagers keep their arms hidden inside their sleeves. All of them, even children. Who doesn't? Oh, yeah, the Wandering Traders(who show their arms but don't use them) and the Illagers inside their mansions who actually wield weapons. And who have blue eyes instead of traditional green eyes. 4. Have you noticed the blatant villager obsession with Emeralds but how they never seem to have any stored themselves? What about in their eyes, which are all green. All emerald green. I doubt that that's a coincidence. 5. The illagers who are very obvious and stated several times as Villager outcasts can build manners and probably constructed Steve(zombie) clones and Creepers(Which would explain why the TNT inside of them is labeled) can do all these things. Maybe it was them building and crafting that got them outcast, maybe it was them trying to build iron golems to protect the village that got themselves outcast. Also, they use axes and crossbows which have to be crafted.

    It really resonated with me, that moment at 3:42:04 , where MatPat buried his face into Peepachu, lingering in the position for a brief moment as he comprehends the contentment of sitting next to the love of his life while listening to the sound of his kid's laughter, surrounded by his found family joyously chuckling along, and a community he knows is present and smiling as well. Moments like these are what makes life worth living. Moments where you don't just feel happy, but content. It's bittersweet to me; I used to have a close friend who didn't have enough of those to keep going. But I hope you all get to personally experience moments like these too. To keep going. To laugh, cry, eat, sing, live. I've been in this community for several years now, and although I've been too shy to actually interact with anyone in it, you all seem pretty nice. Take care of yourselves. I hope you have a good day/night

You always manage to broaden my thinking, give me a smile and occasionally a slight eye leakage. Though it's already been said I'd like to reiterate just how much good you bring to people in a world that isn't always kind. Wherever the future takes you all, know you have done so much, for so many and we appreciate all the efforts you go to for us. Thank you for the last ten years 🥳🤧😭
