It beats the many times I've seen a person walk on to the stage and attempt a joke only for it to fall flat. Devolver puts some proper effort in their presentations to stand out and entertain the viewers.
Humour is subjective, I get that. But compare Ubisoft's to Devolver's and the difference is night and day.
Devolver could come to a conference with absolutely nothing and they'd probably have me laughing in the aisles because they'd twist it into something funny. They've seen an opportunity to use E3 to do something unique and it's landed really well. And they commit to their gags, those fake credits were full of great little nonsense names ("Who puppeteers the puppeteers? - WHOAAAAAAA!"). And when those credits said "Download the soundtrack at...", I broke a huge smile when I found the tweet advertising the conferences soundtrack. Seriously, who does that!?
Devolver Bootleg was very inspired too, and the icing on the gag cake was finding the introductory offer of a 1% discount for that. It's so stupid, it's endearing.
Their conferences work for me because they take many of the negative aspects of gaming and E3 conferences and exaggerates it to a colossal degree. And they're not shy of taking digs at Nintendo, Sony and Microsoft.
It's funny because it's kinda true.
