I was reminiscing about Class of Heroes a week ago so I browsed the wiki and was surprised to know that CoH has an upcoming iteration of the game called Adventure Academia: The Fractured Continent.

Spoiler warning:

Even though the store page and screenshots are in English, it looks like the September release isn't in English yet. As they said it'll be announcing about an english release soon.

The gameplay is vastly different from the former games but I do hope it lives upon the charm of the OGs.

In any case, I do hope CoH 1-3 would release on PC sometime in the future (hoping for a bundle release). I never finished the game but it would be an awesome take to see if it does.
