Co-op in The Sims (GameCube)? Not Supported

The Sims (2003) on Nintendo GameCube is strictly single-player. No local or online multiplayer exists.

What You Can Do

• Pass-the-Controller: Take turns managing the household. Set a timer (15–30 min).
• Shared Legacy: One player builds the house; another plays the family. Swap memory cards to transfer the save (GameCube Memory Card 59/251/1019 blocks).
• Story Collaboration: Co-create narratives—decide careers, relationships, house expansions together.

First Sims Game With Co-op

• The Sims 2 (Console) — PS2/Xbox/GameCube: 2-player split-screen "Freeplay" mode (separate lots).
• The Sims 3 (Console) — PS3/Xbox 360: 2-player local co-op (shared household).
• The Sims 4 — No local co-op. Online via "Share to Gallery" / mods only.

For true shared play today, use The Sims 4 on two PCs/Laptops with a LAN party or Steam Remote Play Together (host streams, guest controls 2nd Sim via mod).
