Games you've played before are definitely easier to watch and appreciate. But sometimes my favorite run at a GDQ is something I wasn't aware of before, and the run just pops off with good skill and commentary.
Super Meat Boy is always an impressive watch. Castlevania games, F-Zero, Mario, Sonic, Donkey Kong.
Also if you wanna laugh, watch the "Awful Games Done Quick" block, starting with Superman 64 and ending with Kevin Costner's Waterworld
nah I enjoy it a lot, and so do many others lol
(their real events, Hotfix not as much)
