Which totally sucks for me, at the moment having an XBox. Still, while you kind of have a point, I don't think it would mean he Baba wouldn't want to.
I mean, it could only really help the franchise get more exposure, even if just with an older protagonist. He probably would be apathetic to it, and mildly surprised if Lloyd somehow got the votes to get Nintendo to ask if they could use him.
This is just me, but I would personally ask them if they'll be any more to the taming of Dinos and other animals than just transportation. Like will there be certain mini-games I can play with them or something like that.
I more said those two because they're solid representations of their genres, which mix well in what ARK is doing.
Even more than that though, I think a whole pack is a bit much, since this isn't a Comic Book fighting game. Even when MK had Scorpion appear in Injustice, he was the only one, and so I do think that would be the case if a character were to make an appearance in the game. Young Wayne and Selina wouldn't fit though, because they're way outclassed and aren't really fighters, and Daredevil belongs to Marvel. Flash isn't really a killer, so that would leave the only believable...
Ya know, it's funny. I hear about how good that movie was all the time, but I've never actually seen it. Though I would question if she's capable of hanging with demons and hellspawn. She's good, but from what I gather, I don't quite think she's a good fit for MK.
I was thinking about including Spawn, but Heihachi got his place on the list. I like and played as both in Soul Calibur 2 and I just thought it'd be a bit shoddy using two characters that guested in SC, but I wouldn't be against having Spawn included at all.
I'm surprised there hasn't been much word for Sea of Thieves, but it's honestly one of the games that is really making me consider getting an XB1.
