Ragnarok Odyssey Ace's partner orgy

Remember in old TV series, when there was a "guest star," "special guest star," "also starring" and "introducing" for whichever names the studio could drag out of the bar that week? Wonder what order they'd go in, in Gung Ho's Ragnarok update which has a chunky list of big and not-so-big guests appearing.

We have:

"GRAVITY DAZE"
"SOUL SACRIFICE"
"Dead or Alive 5 Ultimate"
"Tales of Symphonia Unizo Nantes pack "
"Grandia"
"Emil Chronicle Online"
"Ragnarok Online"
"Keri Princess Suites"
"Puzzle & Dragons"
"Sengoku tenca Triggers"
"Crazy Tower"
"Dokuro"
"Picot Night"

I have no idea how they'll be appearing, or in what capacity, or as playable levels or worlds, characters or bits of equipment. All that is known is that they will appear as DLC over the three months after the game's launch.
