I promise this is NOT an April Fools joke. Kasedo Games is releasing The Metronomicon, a rhythm-based RPG with a lot of big names behind it! Players will fight with your classical RPG character tropes in a club setting whilst rocking along to the tunes of DJ Cutman, YACHT, and Jimmy Urine of Mindless Self Indulgence.
The rhythm element is definitely interesting to me! As weird as it might be the rhythm mechanic would actually introduce some skill behind the simple "click and wait" of normal RPG's. Check out their official page on Steam and wait for it's release sometime this year!
