While RPG Maker MV is still supported and runs well on modern PCs, creating a full MMORPG with it isn't ideal. MMORPGs require robust networking features that RPG Maker MV wasn't designed for.
There are other engines specifically built for online multiplayer games that might be a better fit for your project. If you're still interested in RPG Maker MV for a single-player game, there are RPG Maker MV Battle System Plugins available online that can add complexity and variety to your combat encounters.
