hi everyone we have just launch RPG Maker MZ Plugin: CT Auction House System – Offline AI Auction House & Dynamic Economy
Offline AI Auction House & Dynamic Economy for RPG Maker MZ**
Bring an MMO-style Auction House into your RPG Maker MZ game — completely offline.
CT Auction House System creates a living marketplace filled with AI-driven NPC buyers and sellers that bid, buy, undercut listings, react to market prices, and simulate activity even while the game is closed.
Players can browse auctions, place bids, use instant Buyout, sell their own Items/Weapons/Armors, choose quantities, set prices and auction durations, and track their active bids and listings.

They may return to discover that they were outbid, won an auction, sold an item, or missed a bargain.
Everything runs locally inside RPG Maker MZ.
No internet connection. No server. No API key. No external AI service required.
Perfect for RPGs inspired by MMO economies, crafting games, dungeon crawlers, farming RPGs, merchant games and loot-heavy progression systems.
