Guys, I think I may be Massive Hero Soccer Guy.
Haha, but yea I was thinking Cloud made perfect sense when I realized none of the other 3rd parties besides Mega Man are primarily associated with Nintendo anyways, it's all about iconic status and legacy. That, and picking someone like Cloud is perfect for creating controversy and thus word of mouth. Considering Ryu is promoting Street Fighter V despite its PS4 exclusiveness, I don't see why the same logic wouldn't apply to Cloud.
All things considered, it's pretty hilarious Cloud skipped out on PlayStation All Stars Battle Royale. haha
Okay yeah now looking back at the trailer since I didn't see the whole thing the first time the Midgar stage looks [tornado fang]ing awesome but its too bad it'll be totally unplayable with the ridiculous Spear Pillar esque nonsense going on with all the summons.
I'm guessing Red Materia act like Smash Balls, and whoever breaks it gets to use the summon (or rather, is invincible to it). Pretty cool for casual fun. Probably not so much in 1P modes, especially 8player smash against CPUs.
