Is there a Monster Rancher game created with RPG maker XP or VX?
As of my last knowledge update in September 2021, there are no known Monster Rancher fangames created using RPG Maker XP or VX. However, there are many fan-made Monster Rancher games created with different game engines and tools. Since my knowledge cutoff is limited, there may have been new developments in the fan-made Monster Rancher community. I recommend checking relevant fan forums or searching online for more up-to-date information.
