I quite liked Lylat Wars and had a surprisingly good time with Lies of P, considering I'm not interested in souls-like games.
The highlight for me was the SM64 relay but other than that very little jumped out to me/us (my wife is an avid fan of GDQ too). Love the event but it didn't seem to have anything much for us (like a Mario Maker relay race, rhythm games, that mad Crazy Taxi run with the live band, Spike Vegeta running DKC:R, etc.).
Guess we'll see what SGDQ has to offer!
