Hi guys.
If I eventually post it in the wrong section please feel free to move/lock this Topic.

So I need help to close the gaps of my ideas.

Here what I have:

Players play a game within the game. So basically every Player control two Characters (one in real world (W1) and another in the artificial (W2)). I can handle create the fantasy world (no problem) but I really struggling to elaborate the "W1 activities and goals that aren't boring once all W1 characters are just regular humans.

Additionally I want that something (or someone) in the W1 will attempt to corrupt the mmo game (W2) but I can't find reasons to defend W2 once it would be super simple to just wipe out all data and reupload a new game. Basically I need reason why a villan could destroy the fantasy world and why defend it.

After all that I'm also thinking that at some point the real world characters could start to manifest theirs fantasy world characters' power but I wish it: 1)didn't sound stupid and 2) not every person or country could create a super human being that easy.

I hope anyone can help me.

(Sorry about terrible english)

First off this is going to sound ridiculous but hear me out.  Look up a synopsis of or even watch the last 2 seasons of Riverdale.  They were objectively bad and I only watch it to punish myself for liking TV but I think they did a good "world within a world" thing with a D&D like game being used by a religious cult to get kids to do their bidding, which is in turn being controlled the bike mafia as a way to sell drugs or something, IDK it gets convoluted and is over serious like everything else on the show but that's what makes it camp and fun to watch I guess. 

Anyway, the point is in doing a story like that you need to have that moment where it was all initially presented as fun and games, until it got real...and the guy you thought was in charge actually isn't, maybe the guy who the audience was led to believe was mindless lackey actually is, maybe he isn't, who knows, the point is everything you thought was now isn't, for example thinking it's all fun and games, and that it's not real, because it isn't and is, respectively.
