open moba game with characters from animes/manga, entertainment etc....
a moba for one piece and other anime/manga characters and also for any characters in general like how fornite does it
one piece style would be fighting to destroy the other teams ship for ex.
or just in general a different type of map design but overall to use fun characters and their abilities in a video game
different game modes like current mobas
maybe a battle royale type game mode but with respawns like a coliseum type battle game mode like a big 64 player game mode with/without teams
with maps being able to change throughout the match and have effects on the gameplay
