Granny 1/2/3 (the Granthology) was the best set I saw all week. Speedrunning a horror game can still be scary. The couch was killing it.
Mario 64 Drum% was the best gimmick, even compared to Gyromite Dog%. Though I did get a laugh out of realizing, if Peanut Butter stopped cooperating because he was full, GDQ would have to ban a dog.
Jet Set Radio Future was a good choice for an early run. High-energy, high-speed, broken in some silly-looking ways. Shame about the game's weird blur effects. The spiritual successor Bomb Rush Cyberfunk was good as well.
30XX is absolute chaos with a suitably motormouth runner. The lead dev calls in and doesn't get to say much. (Contrast Doom 2016, where Hugo Martin is just casually chatting, and asks about the background noise like 'are you guys at some kind of party?')
Halo co-op is good fun. Same tier as Aragami: not a must-watch, but definitely a highlight.
Whiplash is a completely bonkers game, in a way that only 2003 could deliver, and it has glitches and sequence breaks that could make Metroid Prime blush. Unfortunately the final boss drags on for being a gimmicky damage sponge. It's twenty minutes of nonstop movement ending with six minutes of waiting.
Some absolute maniac attempted a no-damage run of Resident Evil 2 Remake at a live marathon. You should watch it.
My husband and I watched a bunch of it this year and there was some great stuff on it. Was really impressed by the doom run and the BL2 coop run was easily our favorite with a ton of crazy tricks that made us want to do a new playthrough. The TAS run of super metroid was really cool too. My husband really liked the ocotpath travelr 2 run and I liked the super Mario 2 run.
