How you make a new Marvel Vs Capcom: A Success Story
#1 Reveal teaser trailer with Ryu and Wolverine shaking hands, or possibly Cyclops for XMvSF nostalgia.
#2 Announce with the teaser trailer, a re-release of MVC2, with GGPO online and an even more polished title than the 2008 re-release for all platforms.
#3 Include at least 50 characters from MVCI/UMVC3, the all-stars if you will, and also launch with 10 characters new to MVC, or first time 3D modeled characters for the series, ala Cable/Psylocke.
#4 Make it 3v3 with active tag, remove infinity stones BUT...give players the option of using classic assists as well, design a trade off between the two. Make the game have the best of both worlds gameplay wise, while adding even more crazy shit your team can do.
#5 Make it a celebration of videogames like Smash Ultimate. Classic stages, costumes, music, DLC or otherwise from all the Vs. series back to Xmen COTA. People will eat that shit up.
#6 Finally, make it visually like MVC3 without the caked in black shadows. Go over the top on the comic book artstyle, make lighting look really flashy and action packed, without dipping too far into the manga designed ArcSystem Works look.
#7 Make all the money.
