It's starting with a cross over, but before you know it, Marvel will just buy AoT. Do you know what that means It'll be Disney. And that means... Spoiler
Is it wrong that I would almost want this to be real? Though, there's already Shadow of the Colossus, so wee really don't need another giant enemy boss game
Considering Marvel's already done a crossover with Phineas and Ferb (which was admittedly pretty fun) and Jessie (which is such a stupid show I refuse to even watch the episode and about threw something when I saw the screenshot I was so mad) it wouldn't surprise me if they did.
