I want to acknowledge and share my opinions on cerain subjects of MvC:I
First, the art style.
The art style in all honesty looks fine to me. It's very much in the same vein as Street Fighter V and in that way I was sort of expecting this type of reaction. Street Fighter V looked flat-out ugly when it was first shown, each time we saw it it got better and better but it didn't truly show how good it was until like a month before launch. When we saw Infinite the whole thing looked like it had a filter of piss yellow on it as Maximilian pointed out at the time. The game looks fine right now and will get better and better over the next 5 months.
Second, Sigma.
I get that people are kinda upset about Sigma not being in the base roster and yeah that's warranted and so are the statements that he is a big part of the story like

said. However, I don't feel that you'll be battling Sigma in the story mode and that, all though he is a big part, he himself won't really be all that relevant but Ultron Sigma and Ultron will. That's weird to say but I don't think they would just take a character that's already in the game and just lock him behind a paywall. We all know how that went with Street Fighter X Tekken. I'm not justifying what their doing as right I'm just saying maybe we should all take a wait and see approach, honestly, I'm hyped but if certain things happen to turn out in a way I don't agree with I won't purchase the game. I already made that mistake with SFV.
Third, Fox characters.
There's actually a problem that comes up with every iteration of X-Men or F4 in video games. No matter what, no matter who makes the game Fox will always receive royalties for it. Under their and Marvel's contract Fox is guaranteed to make considerable royalties off of any merchandising associated directly with the X-Men or Fantastic 4. That means toys, cartoons, clothing, and of course, video games. What this means is by cutting Fox characters from the base game Fox will not receive royalties for the entirety of MvC:I. If Fox characters were to be added in the base game Marvel would have to pay a sum for the base game and for ANY content that was added to the game from then on out. A new RE character is added for $5? Yep, Fox gets a sum of money on each sale because even though they have no rights to that character they have rights to a character or two that are in the game and thus receive some of the profit. By limiting Fox characters to DLC Marvel only has to pay for content that is related to the Fox franchises, therefor Fox doesn't make money off of Mega Man or Iron Man etc. It's an obvious business decision BUT that doesn't mean there won't be Fox characters in the base roster. It just seems extremely unlikely. Sony doesn't have that line of merchandising royalties in their contract. Which is why Marvel continued with Spider-man TV shows and toys even when Sony owns the characters rights. Film rights is the only thing Sony owns with Spider-man.
Fourth, DLC.
If we're getting 6 DLC characters then it is safe to assume that 3 will be Capcom and 3 will be Marvel. Of course with my previous explanation of the Contacts it's easy to see characters like Deadpool, Wolverine, and Dr. Doom being the 3. Capcom is a bit of a mixed bag but we do indeed know that Sigma is one of those. The other two are totally up in the air but I would figure they'd go with a character that is HUGELY popular as to warrant the vast majority of players to buy it. I'm not even going to try and guess those characters.
Lastly, release date.
Honestly, I have no idea about this September release date. It's worrying for sure but we don't have any idea how long this game has been in development for. I kinda figure this game started around the same time the Insomniac Spider-man game began development so, like, 2014-2015? Somewhere around there? Which is plenty of time to make a game especially if they're reusing assets from UMvC3. I dunno it's troubling but again, I'll take a wait and see approach to this one.
tl;dr
I'm very cautiously optimistic with this game. I'm hearing things I love and I'm hearing things I hate. I'll hate if they change the inputs from Capcom Fighting Game Inputs to some new **** for sure. It may break the sale for me. However, I can't help but love the general thought of a brand new Marvel Vs. Capcom game with brand new mechanics and characters. So, I'll just have to wait on the Gameplay trailer later this week, then E3, and then launch before I can make my final decision.
