That would be pretty useful, but I understand that finding all the info again/updating old infomation would be a massive undertaking. If there is a way I could help with this I would be happy to give it a go.
I have a Word document full of info/pages I need to update on the Wikia as well and I have been meaning to get around to doing them for a while, so I guess I will start doing them now.
The problem is that I have noticed that when Alex gives out lore information (before it has been implemented into the game) sometimes he changes his mind to something else later, or only an element of the fact stays. I can't think of a more prominent example at the top of my head but I remember when Beowulf was suggested to be 'in his late 20's or early 30's' with 'Mrs. Victoria being older then him'. Of course with Beowulf's bio being released that means that Victoria's age can't be right as Beowulf is 37. It either means that Mrs. Victoria has been aged up (along with Beowulf's suggested age) or just Beowulf has increased in age and Victoria has stayed the same. That or she was made even younger.
Another thing I remember is that 'It would "make sense" if Beowulf has been drafted during the war, perhaps becoming something of a war icon'. Again, it has since been confirmed that Beowulf never fought in the war by Valentine (though his match was a set up to boost war morale, becoming a hero in that way). In this case it wasn't false as it keeps elements and never directly said either-or to begin with (and it said it was undetermined), but it's just another example of outdated stuff. I mean it makes sense as to why it keeps changing (just look at how much different Skullgirls is now as compared to back when Alex first did early drafts for it) and I wouldn't expect any concrete facts at this stage as I just appreciate any insight we can get on the Skullgirls world, but I think that might be the reason why a lot of the information seems muddled (especially the parasite/living weapon stuff).
Oh yeah, I need to update Beowulf's entry in light of his official release as well. Hnnggg.
I totally understand that sometimes Alex changed his mind about stuff (or sometimes even misremembers things) which is why there is a disclaimer at the start of the thread. Like you said, even some info on this thread has been proven wrong or become outdated. The problem with the wiki though is not even that such info pops up, but that sometimes info get added that came from "unreliable" sources. For example, once someone added a fan-made bio of Eliza and added it to her page prior to her release. There are a lot of other pieces of info that originated from (what I imagine are) fan theories and fan fictions that were added as fact to the wiki.
So another problem is, even if we do go through and fix all the entries in the wiki, it doesn't stop people from coming in and adding more "bad" info in the future. These can cause a lot of confusion when these info get displayed alongside "good" info, and some of them are even difficult to identify if you don't follow SG development very closely. The wiki needs a serious and knowledgeable curating team to check any info that is added in the future as well.
Also on a slight tangent, even though Alex made Beowulf older than he said he was previously, it doesn't necessarily mean that Ms Victoria's age has been shifted. If Alex imagined Victoria's age to be the late-30s or 40s, then she is older than him regardless. He never said that she is "slightly" older than him, just older.
Maybe Alex was envisioning Beowulf's age in that answer as the Beowulf who recently defeated Grendel. When you think about it, the recent story revelations showed that his fight with Grendel was in the midst of the Grand War, which would be at least over 7 years ago, probably over a decade ago. The previous age range that he stated would make him way too young for that story to make sense. Judging from Alex's previous answers regarding Beowulf, he didn't have Beowulf's story developed until pretty recently beyond "He beat Grendel and ripped his arm off and went into retirement". If the link between the fight and the Grand War was developed later, then it would make sense that Alex had to shift his age up.
