What is Sven generally excited about ? What does he generally find cool ? We might have a hint there.

I don't remember Sven being excited by former BG lore or FR setting.

But rather about fun or spectacular mechanics (like shove or flying)... or about celebrities involved ? (JK Simmons, Matt Mercer...)
Because of these words : "I just hope people are going to like it because I think it's really cool. Since day one - since day one - I saw people say something", I do not think it is about other celebrities.

So what about things like mounted fight or just mounts to move on the map ? (horse and flying creatures) and/or a fight in Avernus between hell bikes ?

Do you remember other things Sven was really excited to talk about in the previous interviews ?
