CardShopCoop - True Co-op Multiplayer

Run the card shop together.

CardShopCoop turns TCG Card Shop Simulator into a real co-op game: one shared shop, one shared wallet, one shared collection — with both players stocking shelves, serving the register, haggling with trade-in customers, opening packs, and watching the same crowd walk the same aisles.

Built and battle-tested by a dad playing with his son across the room and his brother across town.

Features

• []Steam lobbies — invite from your friends list, or host a public lobby (searchable browser, optional password). LAN/direct IP also supported.[/]

  []Everything is shared — money, shop XP/level/fame, the card collection (graded cards included), item and card prices, shelf stock, card display walls, loose delivery boxes, furniture, licenses, bills, shop expansions, decorations, the OPEN/CLOSED sign, tournaments, card grading, the daily market, and the end-of-day report.[/]

  []Both players actually work — the joiner can serve the register (scan by clicking items or hold V), run customer trade-ins and sell-ins through the game's real trade screen (haggling included), restock, set prices, order stock and furniture from the phone, hire staff, pay bills, and buy licenses. Every action executes in the host's real simulation.[/]

  []Smooth — customers and the other player move on interpolated motion (no teleport-jitter), with real carried items in their hands: product boxes, card fans, binders.[/]

  []Content-mod friendly — made for the PTCGO / Enhanced Prefab Loader ecosystem. The join handshake verifies both players' mod sets and card-ID registries with readable messages, auto-syncs the card database (backs up yours, installs the host's, asks for one restart), warns you in plain language when product catalogs differ, and refunds orders for products the host doesn't have.[/]

  []Joiners risk nothing — the joiner downloads the host's save at join and plays in a dedicated scratch slot. Your own solo saves are never touched, never overwritten, never saved over.[/]
