The issue with the concept at all is that it's a pretty moot point. Tastes may be subjective, but it's a fact that the current 1st party roster is way more low key than the 3rd party one. The whole thing just goes down like:
3rd Party: We have Master Chief, and Lara Croft, and Dante, and 2B, and Crash Bandicoot, and...
Everyone: Oooooh!
1st Party: Oh yeah? Well we have Waluigi, Rex & Pyra/Mythra, and Bandana Waddle Dee! But we'll probably just add whatever shill character we've got cookin' instead...
...
Everyone: So anyway, 1st Parties are a total snooze fest.
So, you might find 1st parties hype, but you're not going to convince anyone because there's nobody to convince them with; Save for arguably Waluigi, there's nobody that even touches the majority of 3rd party candidates.
