Marvel vs DC | Concept Web App: Concept around a marvel vs dc web app or game

A concept I thought about regarding the idea of if we ever had a perfect world... Marvel vs. DC would be an official game. If you'd like to, you can access a short story of why I built this: https://medium.com/@Derrickmv/if... I haven't added a game engine yet so I wanted to start with some character bios and a character selection screen that was reminiscent of classic fighting games such as Marvel vs Capcom, Mortal Kombat, Street Fighter, King of Fighers, Tekken, etc. Although I truly wish it happened, there's still currently no official Marvel vs. DC fighting game in my lifetime. I set out to build this and share with others who hopefully wish for the same thing as me. Thanks so much in advance for your time!
