Yes, indeed. The Re:Zero manga exists and presents the story in a graphical format. It might have some differences from the original source, but it still captures the essence and excitement of the series.
Rockman Online was a game that had an interesting story. It was set in the Rockman universe and likely involved Mega Man's adventures against various robotic enemies. However, the game unfortunately didn't gain as much popularity as expected and was shut down.
As of now, the Edens Zero manga is not finished. The story is still unfolding, and fans are eagerly awaiting the next installments. There's no definite end in sight for the moment.
