To this day I still play a lot of the Dreamcast library on a semi regular basis. And with the upcomign Capcom Fighting Collection 2 its great to see a good majority of the Dreamcast library now on modern consoles, I think Skies of Arcadia is one of the last big ones still stuck on the console.
As for the collab itself I think I did see a few of this leading up the release and I enjoyed them! I assume maybe an OG Xbox collab can be up next considering that some say its a spiritual successor to the Dreamcast!
