Can You Trade PS2 Games for PS3 Games at GameStop?

No. GameStop treats each platform separately. PS2 and PS3 games have different SKUs, value tiers, and inventory systems. You cannot cross-trade between generations.

What You Can Do

• Sell PS2 games for cash or store credit (typically $0.50–$5 each).
• Trade PS2 → PS2 (same platform) for another used PS2 title.
• Sell online (eBay, Mercari) for higher returns on desirable titles (Persona 3/4, Shadow of the Colossus, God of War).
• Buy PS3 games with the credit/cash from PS2 sales.

PS3 backward compatibility (early 60/20 GB models) plays PS2 discs, but that doesn't enable cross-trade at retail.
