What is "Earth-7150?"It is an unofficial alternate universe of Marvel's Earth-616 created by us with its own designation. It covers our
Marvel: Ultimate Alliance game where characters from numerous franchises can appear. We also use this universe to pretend or flat-out ignore some of Marvel's most questionable retcons, as though they never happened. Mostly the ideas of myself and Ceamonks, the majority of our members agree with this.
Yep, that's pretty much it.
So, let's look at what's in our universe...
Spider-Man & Mary Jane are still married. The events of "One More Day" never happened. Many of us feel that Mephisto is not a Spider-Man villain and shouldn't be involved in his stories. That, and the idea that Peter was forced to make a deal and give up his marriage to MJ is just foolish. We'd rather have Peter and MJ grow together and help each other, good times and bad. Spider-Man's taken a lot of losses in his life -- he deserves a win.

While
Knull is the Symbiote God and creator of the symbiotes, the white spider symbol that first appeared on Julia Carpenter (Spider-Woman II/
Arachne) did not come from symbiote dragons. It was simply a cool design that Spider-Man liked during the Secret Wars, and adopted it when the black symbiote bonded with him. We felt it was stupid for the symbol to be connected to symbiote dragons, when there's no explanation as to how Julia had that symbol, as there was no symbiote bonded to her.
Nightwatch was not secretly a villain named "Nighteater" the whole time, who was apprehended by She-Hulk. Actually, the real Nightwatch (who aided Spider-Man in the "Maximum Carnage" story and had adventures of his own) was framed by an alternate version of himself named Nighteater. For more on this in particular, see my fanfiction story that fixes up the ridiculous retcons:

The
X-Men do not live on the living island of Krakoa, and get regrown as plant clones if they die. Never happened. They still reside at or visit the Xavier Institute for the Gifted. We are not fans of the Krakoa storyline mainly because it cheapens death and goes too far away from what made the X-Men and their splinter teams so popular in the first place. We don't mind change... if it makes sense. This one doesn't.
Scarlet Witch and
Quicksilver are still mutants and are still Magneto's children. We know the only reason they retconned it and said they weren't was because at the time, FOX owned the X-Men rights but not the rights to these characters, and they couldn't even be referred to as mutants. But, that's over now. Marvel/Disney owns the film rights to the X-Men, and as such, there is no reason to continue that charade. Pietro has been with X-Factor (one of the X-Men splinter teams), and Wanda -- even though an Avenger, is also X-Men adjacent. Welcome back, mutants.
Captain America never said "Hail HYDRA!" The writer came up with something that angered so many, including us. Later, they tried to save face and said that was actually some an alternate reality version of Cap who became known as the HYDRA Supreme that the real Cap eventually defeated. Fine. In our universe, Cap is still the quintessential hero who at heart is "just a kid from Brooklyn." No recent story will change that.

The hammer of
Thor named Mjolnir did not somehow become sentient after Jane Foster became the female Thor. Odin alone decides who is worthy to wield it. Also, nothing that Nick Fury tells Thor will ever suddenly make him and other gods unworthy. That was a dumb explanation, so we're denouncing that.
Various organizations like the Fantastic Four and SHIELD have access to portal gateways, allowing Marvel characters from another time, planet, or alternate dimension to appear in this universe. The same is true for non-Marvel characters -- whether willingly or reluctantly. Madame Web or the Exiles can allow characters from alternate realities to appear as well.
The Shroud did not retire from superhero work for reasons of insanity. Instead, he got the professional help he desperately needed upon realizing how much his crusade as a vigilante was taking its toll on him. He went to Doc Samson for psychiatric help and ultimately found a new purpose in life. He only comes out of retirement to become The Shroud again for his now wife, Julia Carpenter's, sake.
All of Ceamonks' mods particularly come with a brief story as to how they are playable in this reality. An example of this is that the
Lilandra that's been captured by the Shi'ar (in the game) is not the real one, as she escaped and reached Earth to seek the X-Men's aid. The captured "Lilandra" is actually one of Deathbird's loyal servants disguised as her, in a clever ploy to trick the heroes into saving her and risk getting themselves killed and allowing Deathbird more time to escape. Visit the release posts of his mods to read their particular cases.
(I will add more soon as they come.)
