ZGREATMAGICIAN is the creator of a bunch of projects: Abandoned City is likely his most popular one (and also his best!)
I remember having a brief talk with him back before he removed his original videos from Youtube. He seemed quite ambitious and I must say, now that ambition appears to have come back!
I say that because his Youtube, as of 14/12/19 is back up online, and he's working on a new Reverse Ryona RPG. It's a tad buggy, but overall looks quite promising - more promising than most generic titles on DLSite at least.
For now, I can't wait to see what his game's gonna be like...
