Both are amazing. Both deserve every award that came to them. If you haven't played E33 yet and think it doesn't deserve its accolades, play it. It is worth your money, worth your time, and will in all likelihood prove that it is actually that good. I'm only 10ish hours in and have numerous times found myself standing still and looking around dumbfounded at the gorgeous world design and visuals. E33, Silksong, and Hades 2 could have all won Art Direction and I would have been happy with any of them.
I'm also sad that Silksong didn't win more awards. It's an amazing game. But don't play fanboy and start putting down other developers, other games, and other pieces of art because this one didn't get all the cookies. It's still beautiful, it's still amazing, it still made a Silkskillion dollars, and TC is still just as great and just as passionate. We should all be glad that there is another independent dev out there that is capable of creating something so fantastic.
