Hi Nico, thanks for the info on the PS4 release. I too hope that Kemco continues to release their games on other platforms. If you have a Steam account they do have some games there as well:
Alphadia Genesis
Antiquia Lost
Tears Revolude
And also, Dragon Sinker is listed as “Coming Soon.” (There’s also Asdivine Hearts and Revenant Saga, but you’ve obviously already got those two lol… also Yodanji and something in Japanese – but I personally didn’t care for Yodanji, and don’t know anything about the Japanese game, so…)
Anyway I hope you enjoy Revenant Saga!
